Bugs on aspire one A150

[Maxim Levitsky]

I have just bought an Aspire one A150, XP version,
as it was the only available here, and installed ubuntu on it.

Bugs I discovered so far:


** 1 - embedded controler works in polling mode, due to this:

[    0.708571] ACPI: EC: non-query interrupt received, switching to interrupt mode
[    1.224043] ACPI: EC: missing confirmations, switch off interrupt mode.


Maybe this is the reason for the fact that gnome power manager freezes when I unplug
the AC, and freezes often when I try to see battery status.


(Note: same is seen on my acer aspire 5720)


** 2 - wireless: not to mention the fact that ath5k wasn't installed by default in ubuntu...
wireless more or less works, but kernel log is full of backtraces.
Was able to connect to my WPA2 access point.
Sometimes wireless fails completely, especially after suspend to ram.
Advanced features like monitor/injection work, but when I changed the card's
mac address it stopped working.
I also noticed that if I then start airodump, then wireless works with new mac.



** 3 - internal mic doesn't work.
tried model=acer, model=auto.
Overall it seems that alsa misprograms O/B realteck
codec.
I talk about this later.
Have same issue on my acer 5720



** 4 - wireless led doesn't work.
ath5k devs, can you fix this?


** 5 - coretemp doesn't show cpu temperature,
I have seen somewhere that atom support same thermal diode as core2
and only patch to detect it is needed.
Please include such path in 2.6.28 if exists.


** 6 - both card readers are missing from lspci, is this normal?

** 7 - opengl is broken, I tried running neverball in fullscreen, but it shows wrong/corrupted
textures (compiz is running, and working well thought)
 
Now I installed 2.6.28-rc3 (actually latest -git)


Sadly nothing improved.
I only found few regressions:



* Wireless now drops connection from my WPA2 access point after few minutes.
I changed temporarily its wireless protection to WEP and open mode, and both work
fine, maybe this is related to periodic key exchange WPA does?

* System doesn't reboot/shutdown, just hangs.

That sounds like a known issue.  It has been resolved by "ACPI: EC: revert msleep patch".  Happily Len submitted it for mainline this week.  You will also find it if you try the acpi-test git tree.  We're all hoping 2.6.28 will be much improved in terms of reliable operation of different ECs :).

Well, that doesn't tell us much.  Did they still happen after upgrading to 2.6.28-rc3?  Can we see them?

A similar bug has been reported as a regression:

<http://bugzilla.kernel.org/show_bug.cgi?id=11828>

so one assumes that it worked on the machines with linux pre-installed.  Hopefully without requiring any hacks.

It seems that for now a workaround may be to pass the option debug_quirks=1 to the sdhci module...

<http://marc.info/?l=linux-kernel&m=122509648027303&w=2>

...or that it may help if you insert an SD card before booting.

Apparently the reporter also investigated pcie hotplug.  Probably the BIOS doesn't provide the normal support.  You can try "modprobe pciehp pciehp_force=1", maybe it helps the kernel discover the devices.  It worked for something else on my EeePC.  But then it will reportedly disappear the ethernet controller.

However, at the moment pciehp can cause delays of 10s of seconds during resume.

Could be this:

<http://bugzilla.kernel.org/show_bug.cgi?id=11942>

As a fix, 8fd145917fb62368a9b80db59562c20576238f5a was reverted from the acpi tree.  This has also been submitted to mainline.

Thanks for your work!  If you continue with this, I suggest CC'ing <kernel-testers@vger.kernel.org>.  That will help Rafael the regression hunter pick it up.

Yes, this almost fixes all issues with that.
Almost because, it looks like the EC changes screen brightness on his own when battery is plugged/unplugged,
but so does the gnome-power-manager, and thus it still hangs as before on battery removal (but doesn't hang otherwise)
I disabled that behaver in gnome-power-manager and now no more hangs.

I see that this fix fixes the polled mode. Any chance to make irq mode work?

Fixed completely, looking through the git log I have seen a commit that fixes exactly same backtrace I had.
No more errors in kernel log.

Surprisingly, this is almost fixed.
I can record from both internal mic and external mic
(Quality is not so good, but is the same as in windows)

Almost, is that to increase capture level, I have to set "one" channel of it.
Eg: if I set 100% left and 100% right then capture level is very low.
But when I set 100% left and 0% right or vice versa it works fine.

Also the "mic boost" doesn't change capture volume for internal mic.
also the "mic boost" if set to high value works like analog loopback
(I hear what I say in mic in headphones, same happens on my main notebook acer 5720)

I am aware of this, but don't yet have a SD card to test.

Without compiz neveball works fine (slow, but this is very slow hardware)

Also fixed big thanks.




Also noticed another bug:


If I suspend/resume with compiz running, on resume I see wallpaper and mouse cursor, everything hangs for 
minute or two, and sometimes forever.

2.6.27 worked fine.




Also hibernate doesn't work on my main notebook, but it is probably fixed, I update kernel to really latest -git
and tell you.


Big thanks for bugfixes, you saved me a lot of work and bisecting.

Biggest solvable problem now is sound support now I think, datasheets are there, and
I take a look at them.

Also fixed big thanks.




Also noticed another bug:


If I suspend/resume with compiz running, on resume I see wallpaper and mouse cursor, everything hangs for 
minute or two, and sometimes forever.

2.6.27 worked fine.




Also hibernate doesn't work on my main notebook, but it is probably fixed, I update kernel to really latest -git

Big thanks for bugfixes, you saved me a lot of work and bisecting.

Biggest solvable problem now is sound support now I think, datasheets are there, and
I take a look at them.

Yes, this almost fixes all issues with that.
Almost because, it looks like the EC changes screen brightness on his own when battery is plugged/unplugged,
but so does the gnome-power-manager, and thus it still hangs as before on battery removal (but doesn't hang otherwise)
I disabled that behaver in gnome-power-manager and now no more hangs.

I see that this fix fixes the polled mode. Any chance to make irq mode work?

Fixed completely, looking through the git log I have seen a commit that fixes exactly same backtrace I had.
No more errors in kernel log.

Surprisingly, this is almost fixed.
I can record from both internal mic and external mic
(Quality is not so good, but is the same as in windows)

Almost, is that to increase capture level, I have to set "one" channel of it.
Eg: if I set 100% left and 100% right then capture level is very low.
But when I set 100% left and 0% right or vice versa it works fine.

Also the "mic boost" doesn't change capture volume for internal mic.
also the "mic boost" if set to high value works like analog loopback
(I hear what I say in mic in headphones, same happens on my main notebook acer 5720)

Interesting.  Is it with or without model option?  There is a model
option specific for aspire one (acer-aspire).  Doesn't it work better?

For comparing the hardware setting, please you run alsa-info.sh with
--no-upload option, and attach the generated file at each state.  This
shows the real codec register values.

Also, please run the same procedure for acer 5720, too.

Please do report it as an ACPI EC bug.  It's popular hardware, and if
nothing else it is important that upstream be aware of the workarounds
people are having to use.

Probably not.  It doesn't seem important, it may not be possible, and
even if you could fix the EC driver for your hardware, there's the risk
of breaking other peoples hardware.

The presumption is that you have weird hardware and it genuinely needs a
polling workaround.  It's not too bad, now it uses udelay() it should
not impose any wakeups or significant latency, just some extra cpu time
in a busy loop.  EC events such as acpi hotkeys are still received as
interrupts (although we then have to query the type of event using a
polled transaction).


I assume you get something like (text not exact):

"EC: started in polling mode"
...
"EC: non-query interrupt received, switching to interrupt mode"
...
"EC: missing confirmations, switching to polling mode"

all during boot.


There's one outstanding issue on a different machine, where the
occasional EC read fails and triggers polling mode sometime _after_
boot.  It can be fixed by retrying the transaction

    http://bugzilla.kernel.org/show_bug.cgi?id=11896

but I don't really expect your machine has the same problem.

Did you try sysrq-W during the hang?  That's supposed to dump a list of

Re: [alsa-devel] Bugs on aspire one A150

[Andreas Mohr]

Hi,

[Takashi]:
> Interesting.  Is it with or without model option?  There is a model
> option specific for aspire one (acer-aspire).  Doesn't it work better?

I had already tried 2.6.28-rc3 on A110L (also plus hand-patched digital-mic patch of
patch_realtek.c) and it still didn't work for me.
I didn't use the acer one model parameter, though.

Well, now I just did use it, and it didn't work either AFAICT, with lots
of mixer fumbling again.

And I'm not sure whether the model name should be "acer-aspire" instead
of "acer-aspireone" since Aspire is the name of an entire series
which might possibly have incompatible requirements.
Also, I'm not really happy with the fact that snd_hda_intel doesn't even
log the model name chosen/selected on module initialisation.

Frankly I've had so much snd_hda_intel codec-specific trouble on pretty much all of the
few notebooks/machines that I touched in the last year (that's not an
understatement!) that I think it would be a very nice idea to write a _very_ visible
HOWTO (search words: intel-hda alsa HOWTO codec etc.) detailling how to improve
codec-specific support for snd_hda_intel (this should best be done by explaining
how one arrived at a particular patch for a certain codec, e.g. take the
recent ALC268 work, i.e. check /proc/asound/Intel/codec#0 and look at which part
is not supported by the snd_hda_intel patch file yet and then explain how to add stuff
to it, in very verbose and generic words to let layman people know how to do
this).

As already said, I've (and certainly not only me!) been bitten
again and again and AGAIN by incomplete codec support in snd_hda_intel, thus
we need to make damn sure people can help themselves as well as remotely
possible, to ensure sufficiently fast and sufficiently complete support
for new HDA codecs (which seem to appear each new month or week even,
unfortunately!).
If people don't even know how to tackle this easily, then patch submissions for new
codecs aren't too likely...

And the A110L has been on the shelves for 4 or 5 months already (with 5 to 6
million units sold, they say!!), a time where full support would have been in order.
But it's certainly a major fault of Acer to not have provided full ALSA
support for this (note that I'm not sure about Mic support in its
pre-installed Linpus installation), the ALSA people certainly don't have
any responsibility for this.

Thanks,

OK, _THIS_ time I actually did get the correct model (last time I tried
modprobe with model=acer-aspire, but apparently it then used the
/etc/modprobe.d/ model=toshiba setting, since this time gamix showed
entirely different controls with i-Mic etc.) - all the more reason to
log the model name chosen/selected by the driver!!
--> I have to admit that usability sucks^Hcould be a lot better.
It's perfectly fine for ALSA to not have support for newish codecs or newish
machines with weird setups, but basic usability and or documentation
should thus be as good as can be to make sure that weaknesses can get detected

i-Mic on Ekiga with lotsa mixer fiddling didn't work either this time.

OK, here it is (-rc3 with model=acer-aspire):

Re: Bugs on aspire one A150

[Andreas Mohr]

Hi,

[Takashi]:
> Interesting.  Is it with or without model option?  There is a model
> option specific for aspire one (acer-aspire).  Doesn't it work better?

OK, _THIS_ time I actually did get the correct model (last time I tried
modprobe with model=acer-aspire, but apparently it then used the
/etc/modprobe.d/ model=toshiba setting, since this time gamix showed
entirely different controls with i-Mic etc.) - all the more reason to
log the model name chosen/selected by the driver!!
--> I have to admit that usability sucks^Hcould be a lot better.
It's perfectly fine for ALSA to not have support for newish codecs or newish
machines with weird setups, but basic usability and or documentation
should thus be as good as can be to make sure that weaknesses can get detected
and fixed in no time, even by "interested parties".

i-Mic on Ekiga with lotsa mixer fiddling didn't work either this time.

OK, here it is (-rc3 with model=acer-aspire):

Build with the debug option (why turned off even if you *are*
debugging?).  Then the driver will show you details.

One would call it rather debuggability than usability.
These are completely different things.

OK, then something is missing.  But you should test by arecord first
than any complicated applications as a primary test.

Anyway, the acer-aspire support code was written by Realtek guys, so
it'd be best to ask them...

Build with the debug option (why turned off even if you *are*
debugging?).  Then the driver will show you details.

One would call it rather debuggability than usability.
These are completely different things.

OK, then something is missing.  But you should test by arecord first
than any complicated applications as a primary test.

Anyway, the acer-aspire support code was written by Realtek guys, so
it'd be best to ask them...

Hmm, right, that would have been an (very useful) option, but not for the
majority of users OTOH.
Especially since this is a user-visible module parameter which should thus
be confirmed in mainstream user code, via logging.
Admittedly not many modules log their settings during startup,
but for snd_hda_intel with its two myriads of codec/machine variants
and a resulting quarter myriad of issues that would be very useful.

Good point, will do.

Oh, and is there a way to manually alter codec registers?

Indeed, and far too late (they have submitted it in September I think)
for guaranteeing non-problematic hardware behaviour...
(I'd guesstimate the Realtek submission to be based on Acer activity)
Anyway, still very nice to see that companies do submit patches after all.

Did you get noise calibration failures in dmesg at this point?  Felix posted

Currently all the LED code we have in there is for setting a particular gpio
for particular laptops (and they differ between models).  We only have quirks
for IBM and HP, none for Acer.  Also, the legacy-hal seems to have a different
strategy for 2425 chips.  I can try to hack up some code for you to test.

Yep, but they seems to be gone in latest -git too.
Wireless work fine now, it seems like my iwl3945.

Why it doesn't accept new mac?, can this be fixed?

I have seen on the web that madwifi did support the led with some gpio settings

You can check via /sys/modules/snd_hda_intel/parameters/model whether
you passed correctly or not, at least :)

Passing the model option is already a kind of debugging work, IMO.
You shouldn't do it unless you need it, indeed.

Try hda-verb program.  Build your kernel with CONFIG_SND_HDA_HWDEP=y
and access via the hwdep device.

You can check via /sys/modules/snd_hda_intel/parameters/model whether
you passed correctly or not, at least :)

Passing the model option is already a kind of debugging work, IMO.
You shouldn't do it unless you need it, indeed.

Try hda-verb program.  Build your kernel with CONFIG_SND_HDA_HWDEP=y
and access via the hwdep device.

Hi,

I pretty much studied the datasheet and driver, and this is what I found:
btw, my acer 5720 and aspire one share same ALC268.
Some stuff is trivially fixable, some seems to be unfixable at all:

model=acer is used on my regular laptop.
model-acer-aspire is used on aspire one laptop, and it needs to be renamed, as both are aspire.


1) internal beep volume/mute isn't preserved on resume on acer (I call the big laptop this way).
2) aspire one, has same beep routing, but it isn't supported by this model, it should be added I think.

3) on acer internal mic is mapped wrongly, it assumes that it is a digital mic, while in fact this is
analog mic, and pin configs are set correctly, but they are ignored. fix is trivial, but might break other laptops.
Maybe add this as a new input, like analog mic, at least it can be added for aspire 5720.


4) There is really no internal mic boost on aspire, it is digital, not a bug.

5) Codec supports two ADCs, and so does the driver, but for some models second ADC is ignored.
alc268_capture_alt_mixer is used instead of alc268_capture_mixer.

Here on acer both ADCs are present, and it might be worth to use them both (record from line in and mic)
on aspire one there is only external and internal mic, probably doesn't worth it.

6) Codec supports two DACs too, so it is in theory possible to play different streams on speakers and headphones.
2nd DAC is connected only to headphones, while 1st DAC is connected to all. But here on acer they reversed the connections
and connected speakers to headphones output and headphones to speakers, so probably useless, and besides this doesn't worth the trouble probably.

7) SPDIF is supported on my notebook, but no by the driver, don't yet have a device to test it againt thought, but adding support should be easy.
it is shared with headphones output.
How we can detect that digital headphones are connected, don't know, probably impossible in hardware.


8) The issue of capture volume on aspire one:
when I try to increase internal mic's volume I have to increase ether left
or right channel but not both.

Well, first of all, aspire one mic is really digital.
then, digital mic inputs are supposed to be connected by two mics each resulting in total
of 4 mics.

ADC multiplexers hide difference between analog and digital pins, but of course digital pins
aren't really processed by ADC in analog sense, their input is probably sampled, and digitaly amplified.
Maybe we really need to use only left or right channel there.
I'll test this more carefully.



And now for unfixable problems:

1) There is strong DC offset on all inputs.
it is even different on left/right and depends on capture volume.
I tried to change the VREF only param that could help, but it doesn't.
I feel that this is hardware flaw.
(It is possible that voltage on inputs is created by circuit made by acer, and then ALC268 amplifies it.)



2) That 'analog loopback' when setting any 'boost' setting to high.
The is no mention of that in datasheets, and thus I strongly suspect that this should be called crosstalk.
I understand the block diagram of the chip and there is no loopback, so this isn't alsa bug.


Lastly I noticed that datasheet mentions so called 'coefficients':
the codecs exposes lots of internal and undocumented registers using set address/ get/set value scheme.
maybe some of above bugs are fixable there, but ether realtek has to provide data for that or reverse engineering of
windows driver is required.

(I will test whenever the above happens in windows, at least the #2)

And I hope those registers are for debuging only.

For the reference this this list of nodes on ALC268 (main mobo):

0x01 - params


output streams:
0x02 - DAC1 + volume
0x03 - DAC2 + volume (only headphones)
0x06 - s/pdif-out
0x1D - BEEP


input streams:
0x07 - ADC1
0x23 - ADC1 multiplexer + volume
0x08 - ADC2
0x24 - ADC2 multiplexer + volume


output pins(*):		(***)

0x14 - LINE-OUT		headphones	<- 0x0f - line-out (mixer) <- DAC1 + beep
0x15 - HP-OUT		speakers	<- 0x10 - hp-out  (mixer) <- DAC1 + DAC2 + beep
0x16 - MONO-OUT		N/A		<- 0x0e - mono out (mixer) <- DAC1
0x1E - spdif		


input pins(**):
0x12 - DMIC1/2		N/A
0x13 - DMIC3/4		N/A
0x18 - MIC1		external mic + boost
0x19 - MIC2		internal mic + boost
0x1A - LINE-IN		line-in + boost
0x1C - CD-IN		N/A		


*  Most output pins may be used as input pins
** LINE-IN, MIC1 might be output of DAC1
*** those are pins that are connected on my main mobo.


/proc/asound/card0/codec#0  is attached (also for main computer, I will 
test the 'one' tomorrow

For the reference this this list of nodes on ALC268 (main mobo):

0x01 - params


output streams:
0x02 - DAC1 + volume
0x03 - DAC2 + volume (only headphones)
0x06 - s/pdif-out
0x1D - BEEP


input streams:
0x07 - ADC1
0x23 - ADC1 multiplexer + volume
0x08 - ADC2
0x24 - ADC2 multiplexer + volume


output pins(*):		(***)

0x14 - LINE-OUT		headphones	<- 0x0f - line-out (mixer) <- DAC1 + beep
0x15 - HP-OUT		speakers	<- 0x10 - hp-out  (mixer) <- DAC1 + DAC2 + beep
0x16 - MONO-OUT		N/A		<- 0x0e - mono out (mixer) <- DAC1
0x1E - spdif		


input pins(**):
0x12 - DMIC1/2		N/A
0x13 - DMIC3/4		N/A
0x18 - MIC1		external mic + boost
0x19 - MIC2		internal mic + boost
0x1A - LINE-IN		line-in + boost
0x1C - CD-IN		N/A		


*  Most output pins may be used as input pins
** LINE-IN, MIC1 might be output of DAC1
*** those are pins that are connected on my main mobo.


/proc/asound/card0/codec#0  is attached (also for main computer, I will 
test the 'one' tomorrow

Yes, this is what I see.

Well, I see the wallpaper and can move the mouse, I will try to suspend from console
I think this is graphics bug.
nether ctrl+alt+bks nor SAK kill X.

After 2 minute wait, kernel log doesn't show anything unusual.
printk times, jump that 2 minutes around wireless association, but I tested it without ath5k loaded
and still the same happens.

Also if I disable compiz, everything resumes correctly, and instantly.

Well, this is long story
details at http://lkml.org/lkml/2008/9/20/75
speaking shortly, bios doesn't pass control to kernel on second resume.
Thus I don't test it, but I see how it works now.

Suspend to disk still doesn't work.
First of all system hangs in the end of image writeout.
If I power it down manually, and boot, system resumes from disk, and then hangs.
2.6.27 works fine.

(This is about my main notebook)

Well, I see the wallpaper and can move the mouse, I will try to suspend from console
I think this is graphics bug.
nether ctrl+alt+bks nor SAK kill X.

After 2 minute wait, kernel log doesn't show anything unusual.
printk times, jump that 2 minutes around wireless association, but I tested it without ath5k loaded
and still the same happens.

Also if I disable compiz, everything resumes correctly, and instantly.

Well, this is long story
details at http://lkml.org/lkml/2008/9/20/75
speaking shortly, bios doesn't pass control to kernel on second resume.
Thus I don't test it, but I see how it works now.

Suspend to disk still doesn't work.
First of all system hangs in the end of image writeout.
If I power it down manually, and boot, system resumes from disk, and then hangs.
2.6.27 works fine.

(This is about my main notebook)

Sounds like really bad circuit design then.
One would think that the Intel HDA architecture might have builtin
measures to compensate for this if needed? DC offset issues on
soundcards aren't exactly a new phenomenon after all...

I've actually had a peek at the .inf files since I thought that it would
already contain register values in those registry keys that it creates on
install, but yeah, that's all in-driver it seems.
Probably time to ask Acer about specifics, especially since I didn't spot
any hda-intel changes in their linux-2.6.23.9lw source.

Yeah, we appear to only set the mac address at probe time to the one in the

As a first stab, can you try this patch?  This sets the address on
add_interface and clears it on remove_interface, instead of only doing
it at probe time.  I only compile-tested it.

Small update:

1) The dc offset isn't present on aspire one, really is a circuit design bug I guess 
2) Internal mic works perfectly on aspire one, can reproduce the strange behaver at all,
Probably this was mixer bug.

So aspire one support is almost, only need to add support to restore beep volume
after resume.

Works almost perfectly,


when I load the module, then run macchanger, and then ifconfig wlan0 up
then it works, if I do an ifconfig up once, then ifdowning the interface, it doesn't.

my iwl3945 allows me to

ifconfig wlan0 down
macchanger ....
ifconfig wlan0 up


The noise floor calibration issue bites me again and gain.
When it shows up, usually card continues to work, but at next assotiation stops working.
Maybe this is unrelated, don't know.
Reboot doesn't help, only a cold reboot/suspend to ram helps.
(Module reload doesn't help too).



Transfer speeds are unusually low:
Currently I compile kernel on main laptop, and copy files over nfs to aspire one.
Copying takes ages, and transfer speeds are at 200 Kbytes/s.
(AP isn't involved in direct transfers between stations, right?)

Both notebooks are in same room.


Also noticed, that continued transfer of large volumes (like the above) triggers
noise calibration time-outs, and when it does transfer speeds drop to 50Kbytes/s
Next assotiation usually fails, and only on/off cycle fixes this.

Patch for that does exits, but doesn't apply to latest git,
I will apply in manually.
This should go to .28 I think, this is trivial thing.

Got, a SD card, and with help of pciehp it works almost perfectly in both slots.
Almost, due to the fact that R/O switch is ignored.
(Just as I expected, a s/w switch, couldn't they think more, and include a hardware switch?)
On my main acer R/O switch works.

However I have to use pciehp_force=1, I understand that probably acpi tables are broken,
but could you add a workaround (dmi quirk?)

Also, there is a acpiphp driver, which doesn't work here.
pciehp is supposed to support so called native mode, don't yet know what it is,
but here it still uses acpi.

I almost sure why this happens, opengl application is out of textures,

Patch for that does exits, but doesn't apply to latest git,
I will apply in manually.
This should go to .28 I think, this is trivial thing.

Got, a SD card, and with help of pciehp it works almost perfectly in both slots.
Almost, due to the fact that R/O switch is ignored.
(Just as I expected, a s/w switch, couldn't they think more, and include a hardware switch?)
On my main acer R/O switch works.

However I have to use pciehp_force=1, I understand that probably acpi tables are broken,
but could you add a workaround (dmi quirk?)

Also, there is a acpiphp driver, which doesn't work here.
pciehp is supposed to support so called native mode, don't yet know what it is,
but here it still uses acpi.

I almost sure why this happens, opengl application is out of textures,
I need to install gem enabled intel driver here, and see how it works.

Matthew Garret tells me the Aspire One should be handled by acpiphp
patches he posted on the linux acpi mailing list recently.

I applied his first patch, and now acpiphp works great

Yeah, I had actually written more for that patch originally, but didn't 
post it because it was a bit more invasive.  I think the issue is just that 
start() shouldn't program the mac at all and let add_interface handle that.
I'll post a revised patch in a day or two.

You can try using the minstrel rate control algorithm, it may help.

I'll test this, I guess that it should indeed help.

This actually seems to be iwl3945 bug.

This is the tests I did:


1 . Upload / download from my desktop computer (connected via wired interface)
Speeds are rock solid 1.3 Mbytes/s in both directions

2. Then I tried to upload to my laptop (iwl3945)
Speeds were around 600 Kbytes/s, then after few minutes the ath5k dropped association, associated
again and transfer speed dropped below 64 Kbyte/s
(They didn't stall thought)

3. Then I reloaded the ath5k, it didn't help, 64 Kbyte/s again.

4. Then I tried to transfer files to desktop, 1.3 Mbytes/s again.

5. then tried the laptop, 64 Kbyte/s again

6. Then I reloaded the iwl3945 on laptop, and got 600 Kbytes/s.

It still isn't very clear who is responsible, but this is very fishy.
Maybe the ath5k shouldn't drop association, though.

600 Kbytes/s isn't good ether.


Also ath5k stopped working at all, when I did long test transfer between desktop and laptop, dmesg was full
of some strange message repeated, I haven't been able to reproduce that again, when I do, I will post that message.


In general, ath5k works nice here, big thanks to you for such great work.

Finally, I found how to reproduce that bug,
I mean to get normal volume on internal mic, I have to increase volume
only on left or right channel.

So, this happens always, and _only_ when recording _mono_ sound from internal
mic.

Since hardware doesn't support hardware mono input, tested with -D hw:0
I suspect this to be alsa-lib bug, any ideas?
Happens with arecord -D plughw:0 -c1 .

Wow, nice analysis!
I had already intended to report that you're #2 who told me that Mic does work
(and I was starting to feel weird since I'm the only one who cannot
get it to work!)
Given your analysis, things start to make a lot more sense now.

That probably means that Ekiga Wizard uses mono input (since it does not work
for me), whereas many other apps use stereo input as (natively!) supported
by this hardware setup?

--> alsa lib bug sounds like a good guess.

Thanks,

Andreas Mohr

So, big thanks for everything.

Now aspire one linux support is very close to perfect,
(only problem left is that wireless is limited to 18Mbits/s raw rate,
but at some point I or developers of ath5k will get to the bottom of
this)

I also noticed, that now the SD only card reader is always enabled
regardless of card been there while booting, and same happens in
windows, I suspect that this is permanent hardware change, which worries
me, but this reader works fine otherwise.
(This is another reason why binary bioses are evil, go and find out why
it enables it)


Also forgot to mention that both readers ignore write protect tab on SD
card, and I will report this to correct mailing list soon.
Everything else works fine

please include acpiphp fix in 2.6.28.
Also I applied patch to coretemp to make it show cpu temperature.

Thanks again,

Hi,

Indeed gpio #3 controls the led.
I patched ath5k to use it, and led works now fine.


What I dislike is the way led blinks:

While nether I like constant rate blinking implemented in windows
driver, I don't like the fact that led blinks too fast, sometimes the
blink time is so short that led doesn't show full brightness.

I think there should be a minimal interval for blinking.

Also I don't know what is assumed better, when led is always on, but
turns off when active of vise versa?
(Due to short intervals, when I set it for first option, it is almost
always on, and I almost don't see the interval when it is off)

acpiphp: Identify more removable slots
    
    According to section 6.3.6 of the ACPI spec, the presence of an _RMV
    method that evaluates to 1 is sufficient to indicate that a slot is
    removable without needing an eject method. This patch refactors the
    ejectable slot detection code a little in order to flag these slots as
    ejectable and register them. Acpihp therefore binds to the expresscard
    slot on my HP test machine.
    
    Signed-off-by: Matthew Garrett <mjg@redhat.com>


this makes acpiphp handle hotplug of (now one, sd reader is somehow
always present) card reader.

BTW I looked for settings in EEPROM and didn't find any.

This is something that should rather change in mac80211, I think.  It 
just toggles the state on every packet, and we just do the same when
mac80211 says so (ath5k *could* set up timers like b43, but it's a
lot of extra code, and every driver shouldn't have to do so.)

Then maybe create a whitelist of vendors vs gpio numbers?
Also a module param to set the gpio pin won't hurt.

IWL3945 sets timers too, and this does look ugly.

Also I noticed that sometimes led state gets inverted and it stuck until
I reload the module.

I will, sure.


Just to note, that I might not need that patch as I told that now one of
readers is permanently enabled, I don't know why but this seems to be
hardware failure.

I disconnected power/battery, no cards are in slots, and yet on boot
there is a sd reader in lspci.
Same happens in windows.
It could happen due to suspend/resume, If I remember correctly I put
card once in slot, and then for whole week system wasn't rebooted, but
instead went through suspend/resume cycles.

One thing for sure, nobody will fix this (I mean no point to call acer
support, this is too minor problem)


What I worry about is that second one could show same behavier.
I like this hotplug, as it allows me to test pci hotplug code for real.
Besides, this isn't done without purpose, device might draw less power
this way.

readers is permanently enabled, I don't know why but this seems to be
hardware failure.

I disconnected power/battery, no cards are in slots, and yet on boot
there is a sd reader in lspci.
Same happens in windows.
It could happen due to suspend/resume, If I remember correctly I put
card once in slot, and then for whole week system wasn't rebooted, but
instead went through suspend/resume cycles.

One thing for sure, nobody will fix this (I mean no point to call acer
support, this is too minor problem)


What I worry about is that second one could show same behavier.
I like this hotplug, as it allows me to test pci hotplug code for real.
Besides, this isn't done without purpose, device might draw less power
this way.

I have seen ine gone to 24 and 36 Mb/s, doing a copy in gnome GUI via
sftp (at a couple feet from the router ;).

But at some point, the copy blocked and dmesg said:

ath5k phy0: unsupported jumbo
ath5k phy0: unsupported jumbo

Apart from that, and the led problem, wifi works pretty fine.

Which BIOS ? Mine is 3304, kernel is 2.6.28-rc8, and LEFT card is not detected
unless I use this option:

options sdhci debug_quirks=1

I have downloaded BIOS 3308, but it is to big to fit in my 1.4 floppy image
(I still have a flooy image I dd on a USB flash, but have not managed to grow
it - wouldn't you know how to do it ?)

left read was and does work fine, but before some time it wasn't present
on boot, if there were no card in it, but was hotplugged using acpiphp
when I put it there, but now it is present regardless of card, and I did
no changes in system, so it must be a hardware malfunction/bug.

But how do you load acpiphp ? I try and I just get:

And this is the past one in my list...

With latest updates (kernel rc8, intel video driver 2.5.1, ...), MTRRs are
setup ok:

one:~# cat /proc/mtrr
reg00: base=0x000000000 (    0MB), size=  512MB, count=1: write-back

reg03: base=0x01f800000 (  504MB), size=    8MB, count=1: uncachable

But X still has some kind of problem:

Don't know it its a problem, as DRI works and 'gears' (I know, gears is not

750!!.
Perhaps if X could set its MTRR things would be even faster ??

Sure, will test, I am also sure that this will work.

Unfortunely mac8211 is broken in regard to led handling.

Since ath5k doesn't do timers, led blinks very often, thus usually I
don't even see it, and moreover sometimes it gets 'inverted' and I
tested and this looks like software issue, just writing numbers to /sys
led interface works but triggers from mac8211, they are inverted.

This issue is masked on my iwl3945 since they use mac led triggers only
as a "suggestion" and blink the leds according to their own traffic
measurement, and timers (and still the code that should blink led at
different rates doesn't work, still led ether blinks or not at constant
rate)

Hi,

> Sure, will test, I am also sure that this will work.

A110L, 2.6.28, success (also inverted here, traffic blanks it).

Note that CONFIG_LEDS_TRIGGER_DEFAULT_ON=m, might be related
(possibly ath5k is just mis-using LEDs API, in light of this setting?).

Thanks a lot!

Nope, genuinely inverted,  modprobe ledtrig-default-on and
# echo default-on > /sys/class/leds/ath5k-phy0\:\:*x/trigger
actually blanks the LED.
ledtrig-heartbeat exhibits a weird inverted but actually heartbeat-like pattern,
too.

IOW, our hardware _is_ inverted for real I believe and the driver needs
to be fixed.

Oh, and what about the second LED on the left side? That one would be
available for driver implementation, too, right?
Or is that one hard-wired (via Embedded Controller?)
to rfkill mechanical switch?

(default use for those two would then be rfkill / Rx/Tx triggers, right?)

Thanks for testing.

By inverted, do you mean that it is off when it should be on and
vice-versa?  If so, you can change it to 'sc->led_on = 0' instead
of 1.  Let me know if I should make that change in the patch.

Every laptop is wired differently (in my case I don't even have an LED).
So, you can experiment with different gpios to see if the other LED will
work.  Right now the driver only supports a single led pin but it
wouldn't be hard to change.

Actually, I even thought that this is right behavior, here on iwl3945
led is always on, and blinks while traffic is send, also same on
windows, but feel free to invert the polarity.

What does bother me is, that led state gets inverted dynamically, that
is system starts with default 'led always on', but after some time
switches to 'always led off' and after sometime again switches back.
This does seem to be software problem, at least according to sysfs
interace.

And I think led blinks too fast, sometimes it is hard to even see it.
It might even shorten led life, but this is just a guess.

It's not:
Inversion of the led_on flag does make LED state work properly
and is the right thing to do since an LED
_as seen by the authoritative LED layer_
__has__ to have proper on/off configuration,
regardless of whether having a WLAN LED on-by-default and
off-on-traffic _in the WLAN layer_ is desireable.
(witness wrong state of default-on and heartbeat triggers)

Or, IOW: logical state has to be maintained properly,
at _each layer_ that is involved.

linux/net/mac80211/led.c/ieee80211_led_rx() does simple on/off alternation
via a counter increment modulo, thus somewhat weird LED state toggling
does seem a natural outcome given the current implementation.

I believe the 80211 layer itself should provide some generic LED
handling which then provide for reliable and _identical_ displaying of
WLAN LEDs. It's not a good idea to have individual drivers
mess with custom rssi-indicating LED type implementations,
this should be centralized to have one template for an RSSI LED.

More notes:
. checks of AR5K_NUM_GPIO most certainly are buggy: off-by-1
  (range sems to be 0-5, _not_ 1-6)
. prepend "Acer" to "Aspire One" in this patch
  since Acer is major AR5007EG customer
. testing GPIOs other than 3 (0-6) didn't succeed in making the other
  LED work - what is the behaviour with Linpus, is there an rfkill LED
  there?

Completely agree with you.

Nether does second led works here, even with Win XP that this netbook
came with.

I suspect, that this is usual outcome of an acer tradition, I mean
shipping notebooks with all bluetooch equipment except the actual device
(I mean my notebook has a BT led, BT button, but not a BT device)

I suspect that this led is intended for BT.

Also there is a wireless sign near wireless led, and none near the other
led, and I guess there should have been a BT sign.

Agreed, I suggested this in another thread.  I don't have any LEDs so it 
would be better if someone else did the work.  (I should really build a 
little usb->serial device with a couple of lights on it and hook it up
to the triggers so I can pretend...)

Nice catch, that has been there since day 0.

Will do and I'll invert the logic level in the resend.  Thanks for the
feedback.

Not BT, unallocated 3G socket!
(at least that's what i strongly suspect)

Then the question would be how this is hooked up - hard-wired to 3G
socket or possibly via a function in the Embedded Controller?? (which one could
then abuse for other things)

And many thanks to Bob for his new iteration of LED / GPIO count patches!

OK, I could fully reproduce this now (sorry for the delay!).

Currently 2.6.28, u8.10, model acer-aspire, libasound2 1.0.17a-0ubuntu4,
libasound2-plugins 1.0.17-0ubuntu5.

Recording from i-Mic does work (minus some pretty annoying background noise)
if in gamix I open either left _or_ right channel of the "Capture" control,
but the more both channel sliders progress towards an (almost) equal level,
the more the recording gets reduced to bit changes distantly resembling
the time curve of the recorded signal (but this is not a linear effect,
only the last 5% difference of the slider are dramatic).
IOW you get a "bit buzzing" which clearly distantly resembles the speech
you recorded, something like
"Hello, Test!" --> "crch........crch......crch..."
                   "(H).ee.(l)..oooo..(T).eee.(st)."
I'm wondering whether these are MSB bit, not LSB, remains of the original
signal here... (since they are clearly audible which LSB wouldn't be)

Anyway, we clearly have some differential logic of the two channels
here, which certainly shouldn't be the case, IOW most likely a bug.

I did a diff of the two test logs above, and they were identical.


Ekiga recording test does work with the sliders being opposite,
but audio quality in general is very poor and buggy (only the first
seconds were played back audibly, and in general the speakers have some
background noise which is being switched on/off from time to time at will,
and somehow the whole codec / setup doesn't seem solid).

Any ideas?

Will now try to upgrade to newer ALSA userspace at least.

Same microphone behaviour on 2.6.29-rc8 (additionally remembered to enable
CONFIG_SND_HDA_HWDEP for further testing!), u9.04, model acer-aspire,
libasound2 1.0.18-1ubuntu7, libasound2-plugins 1.0.18-1ubuntu4
(yes, I've just done some monster upgrade).

Will try to eventually analyze things using your _HWDEP-related tools.


2.6.29-rc8, in contrast to several other kernel upgrade occasions,
seems pretty solid so far, BTW.

The question in the top priority is whether it's a kernel driver
issue or alsa-lib converter issue.  Could you check whether the sounds
recorded with -Dhw (and with matching rate, format, etc) have the same
noise problem at first?

And, if it's about the alsa-lib conversion problem, we can reproduce
without the hardware, e.g. via file plugin...

Takashi

OK, tried arecord -v -D hw:0 -c1 test.wav, which ended with
arecord: set_params:961: Sample format non available
.

arecord -v -D hw:0 -c1 -f S16_LE test.wav then ended with
arecord: set_params:966: Channels count non available
thus completing it into a
arecord -v -D hw:0 -c2 -f S16_LE test.wav
worked.

Trying this line with plughw then worked (of course, since two channels
never has any problems).

Interestingly when using plughw there seems to be some LPF effect, since
with hw I get lots of white noise whereas with plughw the recorded sound
is dark (no higher-frequency components at all).

And audio is always being recorded properly no matter which Capture
sliders position.


To state it more clearly, both hw and plughw have no issues whatsoever
with -c2 -f S16_LE, any sliders position.
If I then switch to plughw:0 -c2 -f U8 (IOW change to U8 format),
no problems either. Trouble starts if I then change to -c1 and have
both channel sliders about equal (if they're not equal then I'm getting
audio returned properly).

OK, tried arecord -v -D hw:0 -c1 test.wav, which ended with
arecord: set_params:961: Sample format non available
.

arecord -v -D hw:0 -c1 -f S16_LE test.wav then ended with
arecord: set_params:966: Channels count non available
thus completing it into a
arecord -v -D hw:0 -c2 -f S16_LE test.wav
worked.

Trying this line with plughw then worked (of course, since two channels
never has any problems).

Interestingly when using plughw there seems to be some LPF effect, since

no problems either. Trouble starts if I then change to -c1 and have

So, the following is also problematic

	% arecord -fdat -c1 -Dplughw ng.wav

while the below works?

	% arecord -fdat -Dhw good.wav

Indeed, the above has problems with problematic slider positions whereas
the below never has.

I assume I should be using
sox good.wav -c1 good1.wav
?

If so, yes, this works, audio is there.


Side note: I've got HDA power management activated (with some bad
effects - no sound at all on entire first playback after idle),
but this shouldn't matter here.

Indeed, the above has problems with problematic slider positions whereas
the below never has.

I assume I should be using
sox good.wav -c1 good1.wav
?

If so, yes, this works, audio is there.


Side note: I've got HDA power management activated (with some bad
effects - no sound at all on entire first playback after idle),
but this shouldn't matter here.

Hmm, I thought I was... (elsewhere)

In the problematic case (using plughw),
whenever left channel / right channel sliders are equal, no sound gets recorded.
IOW, there has to be a huge difference (in either direction)
between left and right channel slider to hear anything. And that is Not
A Good Feature to have ;)

Yes but there are many of such :)

More exactly, from the driver perspective, there are no volume
controls but only there are control elements with integer values.
Do you mean "Capture Volume" control or which one?

And, is the behavior consistent regardless of the value high, i.e.
the key is only whether the values for both channels are identical?

BTW, what if you record with the following definition?
Put the below to ~/.asoundrc

pcm.imix {
	type plug
	slave.pcm "hw"

Hmm, ok, this needs to be more precise:
In gamix (codec "HDA Intel : Realtek ALC268"), the Capture Volume control.

Does NOT exhibit the "equal sliders == no sound" bug (apart from this sliders
are acting normally, i.e. slider low == no sound), despite being a
"plug" type definition (this is what you wanted to discern, right? ;).

Yeah, that's more understandable :)

BTW, does "Capture Volume" influence on the recording level even for
the built-in mic, right?  I'm asking this because the digital mic on
STAC/IDT codecs isn't controlled via "Capture Volume" control that is
bound to an ADC widget.  (That's why "Digital Capture Volume" control
exists.  It's a value used by alsa-lib softvol plugin for "default"
PCM.)

Interesting.  This implies that one channel is inverted indeed.
As default the alsa-lib plugin downmixes a stereo stream to a mono
stream simply  by left/2 + right/2.  The above changes the routing
policy as left/2 - right/2.

So we need to pass some information to change this kind of thing...

But a question still remains; why conversion with sox worked.
Maybe it didn't mix?  Or, the code alsa-lib could be buggy...

A simple test would be to just sum all 16bit samples in a stereo
stream file externally.  That is, first record a RAW file via

	% arecord -Dhw -traw -fdat foo.dat

Then create a mono stream just do 16bit left/2 + right/2 calculation
by any way (a good homework for kids :).  Is it also problematic?

Yeah, that's more understandable :)

BTW, does "Capture Volume" influence on the recording level even for
the built-in mic, right?  I'm asking this because the digital mic on
STAC/IDT codecs isn't controlled via "Capture Volume" control that is
bound to an ADC widget.  (That's why "Digital Capture Volume" control
exists.  It's a value used by alsa-lib softvol plugin for "default"
PCM.)

Yes, Capture Volume does influence i-Mic level.
The Digital Capture control, however, doesn't influence level.
As doesn't the Mic Boost Capture control (probably about e-Mic only?).

Oh, you mean "inverted" as in "_hardware_ channel which provides opposite
sample values as compared to the other channel"?

That exactly matches my current stream of thought (while reading
"one channel is inverted" above).

That's something specific to ALC268 codec setup, right?
("ALC268 digital mic == left plus right channel, but inverted setup"?)

The "Digital Capture Volume" has effect only when "default" PCM is used.
If you record via "hw" or "plughw", it's unused.

Right.  My guess is that the hardware provides left (or right) channel
is multiplied by -1  (yep "inverted" is no correct word choice).

I just tried connecting a headset and switching to E-Mic.
What I can say is:
- opposite levels does NOT happen there (E-Mic is "analog micro"-based, right?)
- leaving E-Mic unplugged will actually record from i-Mic (due to properly
  working EAPD mechanism, right?)


BTW, the output (of arecord -Dplughw:0 -c2 -traw -fdat foo.wav) _does_ have
inverted channels:

The record from mic-jack is via analog path.  The phase-inversion
appears only for digital-mic, AFAIK.

My guess is that it's a hardware implementation.
Maybe for the noise suppression via mic array.

The question is whether the left / right channels recorded from
digital mic are really raw data, or they are for modified data
(for differential, etc)...  It's hard to guess without the actual
data.

The mic array on a laptop is used for beam forming and noise
suppressions.  These require the software manipulation, of course. 
The question is what kind of data is read from the hardware.  Thus,
providing the raw streams for both mic inputs makes sense.

Obviously the stream read from the codec chip is a PCM while usually
the digital mic gives the output as PDM.  So PDM -> PCM isn't needed
here.  But, still a question is why a phase inversion in the second
channel.  Whether it's intentional (e.g. to make the further
conversion easier) or not.

Would be interesting if you can figure out which digital-mic component
is used on your laptop (and if we can have any chip information by
luck).

Well, as some manufacturers/types of digital microphones I found Akustica
(AKU 1126 / 2000 / 2001 / 2002 / 2004 / 2103), Analog Devices (ADMP421), National Semiconductor
(digital microphones, amplifiers LMV1024, LMV1026) [1], [2], [3] and
Andrea Digital Array Microphones.

ALC268 specs [4] say that they actually support interfacing
LMV1024/1026, SPD0205ND (what the heck is this one?), AKU2000.

Umm wait, Aspire One has ALC269. ALC269 datasheet doesn't say anything
about microphone manufacturers.

Note that eeepc models 901++ have ALC269 as well
and - surprise, surprise - an inverted noise cancellation issue as well!!!!!:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/331130

"Dreamcom 10 Laptop" [7]: " integrated Realtek HD audio processor, two
built-in Akustica digital microphones and two built-in stereo speakers"

This was the only reference up and down that I could find to _any_
notebook's microphone manufacturer listing. I suspect that
Aspire One has an Akustica microphone array as well since Akustica
seems to be the leading brand (hmm, any ideas about where the
second microphone is located if at all existing, but it must exist!!?
- probably at the front bottom?). 
Note that I found that the 16bit inverted data is NOT exactly a sum
of 0x10000, IOW those _are_ two _separate_, inverted streams of audio data
(for noise cancellation somehow I guess).
OH WAIT!! If most Acer models have _both_ microphones at the screen
bezel (left and right side) yet Aspire One has them (as I'd guess) at

Well, as some manufacturers/types of digital microphones I found Akustica
(AKU 1126 / 2000 / 2001 / 2002 / 2004 / 2103), Analog Devices (ADMP421), National Semiconductor
(digital microphones, amplifiers LMV1024, LMV1026) [1], [2], [3] and
Andrea Digital Array Microphones.

ALC268 specs [4] say that they actually support interfacing
LMV1024/1026, SPD0205ND (what the heck is this one?), AKU2000.

Umm wait, Aspire One has ALC269. ALC269 datasheet doesn't say anything
about microphone manufacturers.

Note that eeepc models 901++ have ALC269 as well
and - surprise, surprise - an inverted noise cancellation issue as well!!!!!:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/331130

"Dreamcom 10 Laptop" [7]: " integrated Realtek HD audio processor, two
built-in Akustica digital microphones and two built-in stereo speakers"

This was the only reference up and down that I could find to _any_
notebook's microphone manufacturer listing. I suspect that
Aspire One has an Akustica microphone array as well since Akustica
seems to be the leading brand (hmm, any ideas about where the
second microphone is located if at all existing, but it must exist!!?
- probably at the front bottom?). 
Note that I found that the 16bit inverted data is NOT exactly a sum
of 0x10000, IOW those _are_ two _separate_, inverted streams of audio data
(for noise cancellation somehow I guess).
OH WAIT!! If most Acer models have _both_ microphones at the screen
bezel (left and right side) yet Aspire One has them (as I'd guess) at
the top of the bezel (known) and at the front bottom, then this would
mean - hold your breath - that the microphone array's physical properties
(regarding noise cancellation) are moved by 90 degrees,
possibly exactly explaining the malfunctioning (this would explain why
Aspire One and eeepcs have issues whereas other Aspire models
probably don't have them!?!?).

NOPE. Aspire One most definitely has a Fortemedia SAM (small array
microphone) due to this output:
http://sites.google.com/site/kengell/acer-aspire-one---dmesg

"
...
ForteMedia SAM-Soft Library Loaded!

ALC INIT

I had already wanted to add the mention of Fortemedia as microphone
manufacturer (forgot this last time), then I researched more and found it.

Fortemedia device names include FM2018-380, not sure yet which one is in
Aspire One.

Searching Google "FM201[0-9] Fortemedia" comes up with FM2010 and
FM2018 and thus
http://www.hengdasheng.com.cn/uploadfile/391/cfile/2008102414057847.pdf

I'm not sure whether FM2018 is on a netbook.  Rather my guess is it's
a digital-mic component by FortMedia together with their software
library for SAM handling.


BTW, a simple "fix" for the mono capture problem, you can patch
the config file for HD-audio in alsa-lib like below.  Then the first
channel will be used for mono capture instead of averages.
Give it a try.

(But, this won't fix programs that prefer "hw" access such as
 pulseaudio, of course.)

No problem.
Lets just lie to usespace that it is mono, in kernel driver can pick one
of channels?

Maybe this is an array, but this doesn't explain the 'quality' of it.
It is so low (in windows too).

No, the hardware provides only the stereo streams, so the driver,
too.

The downmixing is the job of the user-space.  For example, try the
patch to alsa-lib I sent in my previous post.

Properly using the mic-array would reduce the noise fairly well.
XP has no mic-array support, IIRC.

Of course, it's possible that Aspire* have badly equipped mic
arrays that don't help much noise suppression...

No, the hardware provides only the stereo streams, so the driver,
too.

The downmixing is the job of the user-space.  For example, try the
patch to alsa-lib I sent in my previous post.

Properly using the mic-array would reduce the noise fairly well.
XP has no mic-array support, IIRC.

Of course, it's possible that Aspire* have badly equipped mic
arrays that don't help much noise suppression...

I had the same thoughts later. Since they use an extensive SAM handling
library, there probably isn't such a chip, otherwise they probably
wouldn't need it ;)
Could you thus implement a nice beam-forming sound evaluation SAM
library for ALSA pretty pretty please? ;)
...or, is that SAM library available to us given that it exists in the
factory install? If so, then one should probably make good use of it...

I'm not *quite* sure whether this is really what you meant,
but I patched /usr/share/alsa/cards/HDA-Intel.conf (libasound2
1.0.18-1ubuntu7) in exactly this way and then did
arecord -Dplughw:0 -fdat -c1 test.wav; aplay test.wav
but well, with equal slider positions there was no audio again.

An easy one would be a relatively simple algorithm, but I don't know
whether any free library code.  Better to ask on LAD.

Not at the moment at least, sorry. But that would make for a nice
little (student?) project (or not so little).

Tried that, didn't help. /usr/share/alsa/cards/HDA-Intel.conf still
contains the patch, but equal Capture Volume sliders still silenced
audio input, whereas non-equal worked. Hmm.

Yes, that's the very reason.  If you don't PA and avoid the
default configuration override (e.g. defined in /etc/asound.conf)
my patch should work.

Yes, that's the very reason.  If you don't PA and avoid the
default configuration override (e.g. defined in /etc/asound.conf)
my patch should work.

Sorry, but how would I achieve "don't PA"?
I've tried some Ubuntu suggestions
(e.g. http://ubuntuforums.org/showthread.php?t=852518 ; didn't work,
it's Jaunty here),
I tried asoundconf (un)set-pulseaudio (~/.asoundrc contents looked ok
then but didn't really help),
I tried pasuspender -- arecord -fdat -c1 -v test.wav
I always ended up with "ALSA <-> PulseAudio PCM I/O Plugin" mode.
(I didn't even attempt the ultimate solution, removing all traces of
PA packages, since that would be a ridiculous thing to do)
gnome-sound-properties didn't seem overly helpful either...
(Sound capture was already set as "ALSA")

If things are that impractical, then there needs to be another builtin way
to always have the microphone output end up correct, automatically,
instead of having to go through incredible convolutions to try to
access the raw ALSA device (which would probably provide a correct
mic stream) directly, by default.

Or, to put it another way, in many cases the default ALSA device
wouldn't be used (by sound layers or apps or whatever),
thus the patch above wouldn't work there if I'm not mistaken,
thus there needs to be a different way to fix the microphone.

Or, to have it even more condensed, the more you have to fiddle to make
the patch work, the more distance gets between you and the usual Linux
distribution use case.

Any ideas or suggestions?

Thanks,

Andreas

Bugs on aspire one A150

[Maxim Levitsky]

I have just bought an Aspire one A150, XP version,
as it was the only available here, and installed ubuntu on it.

Bugs I discovered so far:


** 1 - embedded controler works in polling mode, due to this:

[    0.708571] ACPI: EC: non-query interrupt received, switching to interrupt mode
[    1.224043] ACPI: EC: missing confirmations, switch off interrupt mode.


Maybe this is the reason for the fact that gnome power manager freezes when I unplug
the AC, and freezes often when I try to see battery status.


(Note: same is seen on my acer aspire 5720)


** 2 - wireless: not to mention the fact that ath5k wasn't installed by default in ubuntu...
wireless more or less works, but kernel log is full of backtraces.
Was able to connect to my WPA2 access point.
Sometimes wireless fails completely, especially after suspend to ram.
Advanced features like monitor/injection work, but when I changed the card's
mac address it stopped working.
I also noticed that if I then start airodump, then wireless works with new mac.



** 3 - internal mic doesn't work.
tried model=acer, model=auto.
Overall it seems that alsa misprograms O/B realteck
codec.
I talk about this later.
Have same issue on my acer 5720



** 4 - wireless led doesn't work.
ath5k devs, can you fix this?


** 5 - coretemp doesn't show cpu temperature,
I have seen somewhere that atom support same thermal diode as core2
and only patch to detect it is needed.
Please include such path in 2.6.28 if exists.


** 6 - both card readers are missing from lspci, is this normal?

** 7 - opengl is broken, I tried running neverball in fullscreen, but it shows wrong/corrupted
textures (compiz is running, and working well thought)
 
Now I installed 2.6.28-rc3 (actually latest -git)


Sadly nothing improved.
I only found few regressions:



* Wireless now drops connection from my WPA2 access point after few minutes.
I changed temporarily its wireless protection to WEP and open mode, and both work
fine, maybe this is related to periodic key exchange WPA does?

* System doesn't reboot/shutdown, just hangs.





Best regards,
	Maxim Levitsky.
