This fixes issues with M-Audio's Fast Track Ultra series:

* devices now work at 44100 and 88200 Hz
* apparently, fixes some crashes, too

This is based on a patch posted by user 'dhubsith' on the M-Audio user 
forum.

Sorry for not sending via 'git send-email': I just don't get it...

Kind regards,

Felix

Re: [PATCH - Fix Fast Track Ultra series: 44.1/88.1 kHz 1/Fix playback/capture issues and related chrashes at 44100 Hz and 88200 Hz for M-Audio Fast Track Ultra series.

[Felix Homann]

Hi,

Here's a slightly updated version of the patch. It does essentially the 
same as the former one but sets the capture endpoint attribute to 
'async' and the playback endpoint to 'adaptive'.

Kind regards,

Felix

The descriptors already list these rates, so in theory, the existing
code that sets UAC_EP_CS_ATTR_SAMPLE_RATE should already have enabled
this.  Didn't it?  In other words, what is the difference in the
explicitly specified audioformat?

(I have the suspicion that we don't actually need a AUDIO_FIXED_ENDPOINT
quirk for these devices.)

When do these crashes happen?

If you don't have the exclusive copyright for the code in this patch,
there needs to be a Signed-off-by line from him, too.  OTOH, a table
like this probably isn't copyrightable at all.

This replaces the ID of the Ultra 8 ID with that of the Ultra 8R ...

... and this just changes the other 8R entry.  So now the 8 doesn't
have an entry.

I can only tell you the difference to the behaviour of latest git Alsa 
before this patch:

44100 and 88200 Hz had already been enabled. But the device could not 
properly be used at these sampling rates. Everything would sound 
distorted. After a while of running the device at these sample rates, my 
systems had a tendency to crash/freeze.

> quirk for these devices.)
>
>    

Something must be in this AUDIO_FIXED_ENDPOINT quirk, since the device 
now works properly and stable @44.1/88.2 kHz. I don't know the exact 
reason, since I really don't understand all this stuff. I just have this 
device and try to fix it's behaviour.

>> * apparently, fixes some crashes, too
>>

>    

See above: System crashes occured when using the device at 44.1/88.2 kHz.

If the patch is copyrightable then its copyright belongs to you: The 
patch I send some time ago to enable basic support for these devices was 
an updated version of *your* patch send some time ago to a mailing list. 
The patch dhubsith posted was explicitly based on existing code in 
quirks-table.h and the existing quirk.

Take a look at the entry for the Digidesign Mbox (credited to you): It's 
essentially the same.

Ooops. I've messed it up... (I've just got the 8R version so I didn't 
notice...)

Actually both quirk blocks shoud be the same except for the USB_DEVICE 
lines:

USB_DEVICE(0x0763, 0x2080) <- Fast Track Ultra
USB_DEVICE(0x0763, 0x2081) <- Fast Track Ultra 8R

(Actually there's no "Fast Track Ultra 8")


Sorry for having messed the patch up and sending it too soon. Shall I 
send a new patch, or would you consider manually editing it yourself 
before eventually putting it into git?

Kind regards,

Felix

Hi,

here's the hopefully corrected version of the patch.

Furthermore, I got notice from dhubsith that he would sign it of if 
needed. What do you think?

Kind regards,

There must be some difference, and I'd really like to know what it is.
Please load the driver with the patch below, with and without the
AUDIO_FIXED_ENDPOINT patch, and show what it prints to the system log.

Sorry, the call for the case without the fixed quirk is buggy.
In line 199 of format.c, please change "fp->rates" to "fp->rate_table".

Hmm,

I guess  there's still something wrong with your debug patch (or me 
applying it...). Doesn't look like any valuable information in syslog 
this time (no fixed_endpoint quirk):

But that part of parse_audio_format_rates_v1 definitely gets executed,
or the kernel wouldn't have crashed previously.

Please make sure that the source code (in alsa-kernel) contains the
print_hex_dump_bytes call, and that it is this driver that gets
loaded.

Hi Clemens,

Have you found what's making the AUDIO_FIXED_ENDPOINT necessary? What 
are the chances for the patch to make it into the git repositories 
otherwise?

Kind regards,

Dear Alsa developers,

almost 2 months ago I send a patch making the M-Audio Fast Track Ultra 
series audio interfaces work flawlessly in Linux except for missing

Unfortunately, the patch didn't make it into Alsa so far. Clemens 
Ladisch seemed reluctant to apply a fixed endpoint quirk since the 
device should have worked without in his opinion. I gave him all the 
requested information to see what was happening without the fixed 
endpoint quirk. I never heard back from him again.

So, could someone in charge kindly tell me why the patch didn't make it 
into Alsa? What's missing, what's wrong?

If it's just the fact that Clemens doesn't like the fixed endpoint quirk 
please find attached a different patch yielding the same result. 
(Against Linux 2.6.35. It's again from dhubsith who posted it on the 
M-Audio forum. He would sign it off if requested - on the other hand it 
is already derived work of the Alsa sources).

And please, if it's not going anywhere, please tell us "laymen, 
volunteer Alsa helpers" about the reasons.

The current situation is most frustrating: We know how to make the 
device work (much better than in Windows, btw) but we don't know why we 
have to patch alsa again and again.

Thanks in advance,

Felix

Could you include the link to the forum post.

I guess his signed-off-by line additionally to yours (Tested-by: is also
good) would not hurt.

Sorry, unfortunately I cannot tell you why your work has not been
committed yet and I do understand your frustration. The reasons might be
simple, that the developers were caught up by different things and your
patch just fall through the cracks. So it is a good thing, that you come
back and ask for the status.

So to ease work for the developers, could you please resend your patch.
Do you know if it can be split up, so that the controversial parts can
be left out at first?

Please use `git format-patch` with

1. a short commit summary line,
2. links to the respective Web pages where this patch was discussed.

You can just copy the lines from the resulting file into a normal
message (delete the header fields and copy the subject manually marking
it with [RESENT]). Just make sure the lines do not get wrapped.

Then make sure to CC the maintainers (I think Clemens, Takashi,
Jaroslav) too so that they do not miss it.

I hope your patch will be included soon afterward.


Thanks and good luck,

Paul

[RESENT] [PATCH - Fix Fast Track Ultra series: 44.1/88.1 kHz 1/Fix playback/capture issues and related chrashes at 44100 Hz and 88200 Hz for M-Audio Fast Track Ultra series.

[Felix Homann]

[-- Attachment #1: Type: text/plain, Size: 1922 bytes --]

Hi,

This is my second try to get support for all supported sample rates for 
the Fast Track Ultra (FTU) series into mainline alsa.

For clarification: Current Alsa already recognizes the supported sample 
rates. But it will sound very corrupted at 44.1000 Hz and 88.200 Hz. 
Without this patch your system will even probably freeze eventually when 
using the FTU at 44.100/88.200 Hz too long.

So the key idea in this patch is not to get 44.1 kHz and 88.2 kHz listed 
as supported sample rates (as they already are recognized) but to change 
the endpoint attributes.

Citing dhubsith on the M-Audio forum:

" The problem with using QUIRK_AUDIO_STANDARD_INTERFACE rather than 
QUIRK_AUDIO_FIXED_ENDPOINT is that ep_attr does not get set correctly. 
The device default for synchronization is async (0x05) for both capture 
and playback, but in fact it should be set to adaptive (0x09) on 
playback, so that playback follows capture, this way you don't get 
capture and playback using different sample rates.

Also, the Interface Class protocol for the device defaults to Vendor 
Specific Class, but the driver only recognizes Class 1 or 2. The device 
is really Class 1, so we have to force it to reflect this. There are 4 
places that we need to set this."



The patch has been discussed starting here:

http://forums.m-audio.com/showthread.php?714-Not-a-problem.-FastTrack-on-linux/page8

The "key" has been found by dhubsith. Please read posts #79, #81, #84, 
#87, #97.


In post #102 of that forum you can even find an alternate patch by 
dhubsith which doesn't use a fixed endpoint quirk but sets

      protocol = UAC_VERSION_1;

for the FTU devices in sound/usb/format .c. You might even consider that 
patch. (I've resend it to alsa-devel yesterday).

After all, either one of the above mentioned patches should go into 
alsa, as right now we can't use the FTU devices at 44.1 and 88.2 kHz.

Kind regards,

Felix

Thanks for the patch (and reposting it).

I myself find it's OK to apply since it's pretty local change.
Clemens, what was your objection at that time?

No objection per se, I wanted to find out what descriptor field is
changed by the quirk, and where the crashes come from exactly.  The
latter is still unclear, but it seems a quirk like this is required.

I've committed the patch now.

Daniel, this seems to be a regression introduced with the UAC2 changes.
The old driver accepted vendor-specific interfaces, if some quirk forced
it to look at them.

Hmm, I don't follow. What's the problem, and why should that be caused
by the UAC2 changes? Sorry, but I seem to have missed that thread.

I've got several reports that devices no longer work since UAC2 support got
added.  But I've just noticed this is not related to the interface class
but to the interface protocol: the new code added checks for UAC_VERSION_1
or _2, but real devices apparently write just random junk into this field.
(For vendor-specific interfaces, they are actually justified to do so.)

Grr. So what about cases where this "random junk" is 0x20 by coincidence?

We could also fix up such devices with quirks tables, but your approach
is probably better as it catches all devices right away.
