Re: ALSA Config

I noticed that this error came up on boot:
alsactl restore error message alsactl: set_control: 1269 : Failed to obtain info for control #24(no such file or directory) when it was trying to start alsa. So its to do with alsa not being able to restore the previous volumes properly.

Nigel here is the information you wanted.
dean@debian:~$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.16.
dean@debian:~$ uname -r
dean@debian:~$ grep ^Codec /proc/asound/card?/codec*
/proc/asound/card0/codec#0:Codec: SigmaTel STAC9228
/proc/asound/card0/codec#1:Codec: Conexant ID 2c06

BTW that is the problem as all the modules are loaded and unloaded successfully. I am unable to boot in to previous kernels as i have removed them(d'oh, stupid me).

Hi Dean.

I havn't played around with alsa unload/alsa resume before, but when you
reboot, are the alsa modules loaded again (lsmod | grep snd), and is the
soundcard detected, as when running.
cat /proc/asound/cards

Don't post the output, a yes, or no is ok.

Also please post the output of the following.

cat /proc/asound/version
uname -r
grep ^Codec /proc/asound/card?/codec*

There are some model options for the STAC9228 codec, as listed below. Try them
out one at a time in /etc/modprobe.d/alsa-base, and obviously reboot to try
each one.

  ref  Reference board
  3stack D965 3stack
  5stack D965 5stack + SPDIF
  dell-3stack Dell Dimension E520
  dell-bios Fixes with Dell BIOS setup

The "ref" one is the default, but try the others. The above options are for
the alsa driver 1.0.17, and also apply to alsa driver 1.0.18a.

Example options line below.

options snd-hda-intel model=3stack

I'm thinking that there may be some slider missing in alsamixer when you boot
the machine up, but when you run alsaconf, for some reason or other the
correct mixer elements are displayed in alsamixer, which is why the sounds
then work.

If you have an earlier kernel installed, try booting with that, as some
kernels can have problems with sounds.

Just some suggestions from someone trying to help others to get sounds
