Hi,

Since last upgrade I have no sound anymore.
Here is the output of lsmod | grep snd :

My card is correctly detected as Intel Corporation 82801DB/DBL/DBM
but at the end of the alsaconf procedure I get:
 
Running update-modules...
Loading driver...
Usage: /etc/init.d/alsa

Setting default volumes...
amixer: Mixer attach default error: No such device
Saving the mixer setup used for this in /var/lib/alsa/asound.state.
/usr/sbin/alsactl: save_state:1253: No soundcards found...

And no driver is loaded

Please check #428454, which started similar. Do you have a
~/.asoundrc? Do a backup, delete it and try again.

Subject: rmmod snd_via82xx && modprobe snd_via82xx
Date: Fri, 22 Jun 2007 08:47:04 -0700
My computer has also started going silent recently.

I currently work around the problem by 

1.) Closing audio applications,

2.) typing this as root 

    "rmmod snd_via82xx && modprobe snd_via82xx"

3.) and restarting the audio application

If anyone happens to know why, I'd appreciate an
explanation.

The two workarounds mentioned in bug report
#428454 didn't work for me.

These versions were installed on my computer, but
I may upgrade some soon

Your installation seems to be a chaos which should be sorted by a
clean update/upgrade first!

Dear Elimar,

You're not the first person to recommend an
upgrade, and I'm sure you won't be the last.

Here's the big but.

BUT, "apt-get check" reports no broken
dependencies, and an "apt-get upgrade" might

a.) obscure a bug that should be fixed and

b.) install packages with new bugs.

Also, it seems to me that upgrading everything
would be a throw back to the old days before
Debian wisely implemented finer grained
dependencies between individual packages.

I'd prefer to find the real bug and fix it.

Thanks,
Kingsley

Looks like you're running etch? Please install at least:

apt-get install -t stable libasound2 alsa-utils alsa-base alsa-source

Remove old alsaconf, which isn't really needed:

apt-get remove --purge alsaconf

If you're using Debian's kerneldrivers, your soundcard might be
usable now. Otherwise build your soundcard with fresh intalled
alsa-source package.

Hey, Iam running sid (unstable) on servers. Very stable, man ;) Your
installation is mixed up back from woody to some lenny packages.
Maybe there are some Potato packages flowing around ?  I am
wondering whether this works anyway. You're done with an apt-get
update && apt-get dist-upgrade. If you then have ALSA probs, you're
welcome to help you ;) But your mixed up installation isn't
supportable for a maintainer, though.

I'd like to check for a certain bug.

Does any ALSA expert happen to know whether
there's an easy way to compile ALSA with the

    CONFIG_SND_DEBUG

and

    CONFIG_SND_VERBOSE_PRINTK

debugging flags set, ideally so that 

    $ module-assistant a-i

uses them?

If so, how?

Thanks,
Kingsley

  Then you are using unsupported mixes. Debian distributions are a
whole, and tested as such. It means that if you do cumbersome mixes of
libraries from old stables with the new one, you'll definitely
experience issues. They won't be addressed anyway, as the maintainer
does not has time to test every combination users could have think of.

  Anyways, there is no way this bug is RC, downgrading it as
appropriate.

Do you have sound now? If yes: How did you managed it?

At least on my computer, it seems to me that this
bug turned out to be caused by flaky hardware.

In the interest of possibly helping someone else
who happens to encounter it, here's how I recall
that I worked around, diagnosed and ultimately
fixed my bug.

I worked around it by typing this as root whenever
audio stopped working:

    $ for control in Master PCM CD ; do amixer set $control mute ; amixer set $control unmute ; done

I diagnosed it as a hardware problem by 

a.) adding "printk()" statements to anywhere in
via82xx.c and ac97_codec.c that looked like they
might reset audio, 

b.) recompiling by running the following command
as root:

    $ m-a -f -v -O a-i alsa

and then monitoring the printk()'s with something like

    $ cat /proc/kmsg | while read a_line ; do echo $(date +%x:%T) "$a_line" ; done

and 

c.) checking for diagnostic printk() messages when
audio spontaneously stopped working. None
appeared, which makes me suspect that the sound
hardware, AC97 on the motherboard, was
spontaneously resetting, unrelated to any alsa
bug. (Coincidentally, my computer's audio started
spontaneously resetting at about the same time
that I replaced a Buslogic scsi host adapter with
a used one from Adaptec. I had encountered an old
bug in the unsupported Buslogic driver that broke
my computer's scanner.)

I ultimately fixed the audio bug by installing a
sound card. 

As an aside, the new sound card seemed to cause
the kernel to crash with

As told before:
dpkg-reconfigure alsa-source and answer the second question
corresponding to your wish.

And hey, this has nothing to do with #429784!
