PC speaker beeps in 2.6.30?

PC speaker beeps in 2.6.30?

[Michael Tokarev]

Anyone know what happened with PC speaker in 2.6.30?
Basically, it does not work anymore here, with the
config which is very similar to the one used for
previous 2.6.29 kernel (where PC speaker worked).
At least I don't see any relevant differences and
the (seemengly) relevant symbols -- which are
INPUT_PCSPKR and PCSPKR_PLATFORM -- are both set
to 'y' for both 2.6.29 and 2.6.30.

Help? :)

Thanks.

For me the system beep has been replaced by a beep in ALSA with .30.

Do you have soundcard that uses HDA? Is CONFIG_SND_HDA_INPUT_BEEP set?
Does alsamixer show a "beep" control? Is that not muted and does it have 
volume set?

I had this exact same problem. I ran make oldconfig and was never prompted 
for the new HDA config options. I could be wrong, but I can't remember 
make oldconfig behaving this way in the past (or maybe it resulted in 
changes that didn't have any noticeable effect). Having to reconfigure 
the kernel over not being prompted for a new config option which changed 
established behavior was annoying to say the least.

Hmm...

..Yes there is such a control and yes it is muted.  When un-muting it I do
hear an ugly/scary beep from my soundcard (from the speakers).  But I don't
have anything connected to the soundcard on any of my servers.

On a similar motherboard with 2.6.29 I've a "PC Speak" control which does
not do anything, at least not visible (or audible).

But I'd rather get my old good pc speaker back.  One thing is the sound
card with speakers which are only sometimes on and which produces very
very bad sound when the 'beeper' control is turned on, and another is the
old good PC internal speaker with a good "beep" sound.

Thanks!

And this same config option (CONFIG_SND_HDA_INPUT_BEEP) is present in
2.6.29 kernel.  Also set to y here.

As I noted in my other email, this option (CONFIG_SND_HDA_INPUT_BEEP)
is not new, it is present in 2.6.29 too.  So it's a behavor change which
is not "backed up" by a config option -- there's no option to prompt
for.

[Adding some more Cc's...]

Am I the only concerned about this?  My 2.6.30 is still
silent w.r.t. old good PC speaker beeps, and I wasn't
able to make it to produce any sound.  Yes, as pointed
out by others there is a control now, in alsa, and I
can hear ugly and scary beeps from my stereo speakers
(when they're turned on and when the control is un-muted).
But that's.. not a solution/answer to the original
question... ;)

Thanks!

Try 2.6.31-rc1.  There was a fix regarding beep frequency.

You mean this one:

commit fa7979663190240b838ab8c8bad7f59e618bf77c
Author: Takashi Iwai <tiwai@suse.de>
Date:   Tue May 19 12:50:04 2009 +0200

     ALSA: hda - Fix digital beep tone calculation

?

Note it's about alsa/hda beep.  Probably to make my new
"alsa beeps" less scary.  But I'm asking about PC speaker --
see the $subject line.  I'm missing PC speaker beeps, not
alsa beeps.

Thanks!

Not necessarily.  Based on the OP's original post, as well as his mails
to the LKML (Google the subject line to find them), he has a desktop
system with external powered speakers connected to a sound card, and also
a small PC speaker inside the system case.  He wants to hear the beeps
coming out of the small speaker, since the external speakers (and/or sound
card) are not always turned on.

For that, try turning off SND_HDA_INPUT_BEEP.

(Regarding the beep frequency issue, the patch in 2.6.31-rc1 works for
all HDA codecs *EXCEPT* sigmatel/idt.  For sigmatel/idt, please see the
patch in bug #0004556.)

To avoid someone misunderstanding: the beep routed through HD-audio
can also go to the built-in speaker.  It's just mixed up with the
normal audio output, and the volume is controlled via ALSA mixer 
volume element.

But, once after it's hooked up to the codec, the beep can't be output
separately to the speaker.  It's always with other audio signal to the
same output target.

Or, on some systems (mostly laptops), the beep is hooked up to the
codec automatically no matter whether you set
CONFIG_SND_HDA_INPUT_BEEP once when the codec chip is initialized.
So, the behavior depends pretty much on the hardware implementation.

I face the same problem as the OP since kernel 2.6.30 on ArchLinux on
a desktop machine. I was able to get beep working through the built in
speaker again by doing a 'modprobe -r pcspkr' followed by a
'modprobe pcspkr' after sysinit. It seems there is some kind of
struggle goinig on here between alsa and pcspkr. Isn't there any
kernel line or modules configuration option to disable the alsa pc-beep?

Did you actually try compiling a kernel without CONFIG_SND_HDA_INPUT_BEEP 
set? If you do, does your PC speaker work again?

If it does work again, I don't think there is a bug, at least not in the 
fact that the old PC speaker beep no longer works: if you have a HDA 
soundcard in the system _and_ the driver is loaded _and_ 
CONFIG_SND_HDA_INPUT_BEEP is set, then it seems logical to me that that 
takes over system beeps.
The fact that the config option also existed in 2.6.29 but did not work 
the same seems a minor issue to me.

If your PC speaker still does not work when CONFIG_SND_HDA_INPUT_BEEP is 
not set, then there is something to look into.

> and I can hear ugly and scary beeps from my stereo speakers

This may be a separate issue. On my system the beep sounds "normal". It 
has been changed in 2.6.31-rc1 to a slightly lower sound.

What exactly do you mean by "ugly and scary"? I have the volume for the 
beep set to about 50% because otherwise it is just too loud. Have you 
tried that?

If it really does sound bad, maybe the ALSA developers could look into 
that, but you will have to describe it better (or maybe make a 
recording?).

Yes it works.  Even with CONFIG_SND_HDA_INPUT_BEEP set,
but without the module loaded.  See all the details at
http://bugzilla.kernel.org/show_bug.cgi?id=13651

Original issue was that I didn't know what to do.

There was another, unrelated bug, fixed for 2.6.31-tobe.

Hm... apparently not.  Probably there should be a module option for this, though.

In the latest sound git tree, you can use "patch" file (passed via
module option) to specify codec-specific setup.
It's for 2.6.32, though.

Sounds rather complicated to me. :)
ALSA's snd-hda-intel is stealing the beeps allready 'owned' by pcspkr. 
It does
this every time it gets [re]loaded. Doing so while lacking a 
configuration option
to disable that behavior is a bug IMHO. (If you use beep to get some alarm
notification from hardware sensors or such you will depend on stereo 
speakers
connected and powered on.) Do I miss something ?

It just adds another beep input device.

There is a configuration option.

But you can do it via patch module option (in the later kernel).

Yes.  It's a designed behavior.  One calls it a "feature".
A feature can be of course bad, worse than other behavior.
