Hi Everyone,
I've been trying to get help on ALSA mailing lists, Debian IRC
channels and forums with no success.
Every time I boot my Debian Sid box I don't have sound until running
'alsaconf'.
Well, here we go, again:
I've just rebooted my system.
# [EMAIL PROTECTED]:~$ lsmod | grep snd
# snd_hda_intel 434776 0
# snd_pcm 81672 1 snd_hda_intel

My driver is the snd_hda_intel for this soundcard here:
# [EMAIL PROTECTED]:~$ lspci | grep -i audio
# 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD
Audio Controller (rev 02)
It's loaded, but no sound.
Which application do you use to test that?
Rhythmbox and Totem. I tried speaker-test once with the same results in
this thread.
OK, so we know that the problem is not limited to desktop applications;
it seems to be a general issue with ALSA.
All these applications behave as they were playing something, but no
sound comes off. Everything seems to be a volume problem, but all the
channels are always unmutted.
You can do this:
amixer > before.txt
before you run alsaconf and afterwards you run
amixer > after.txt
and compare the mixer settings with
diff -u before.txt after.txt
to make sure that the difference is not due to some semi-obscure control
that you overlooked.
There's no difference between these two outputs.
Then trying to start ALSA:
# [EMAIL PROTECTED]:~$ sudo /etc/init.d/alsa-utils start
# Setting up ALSA...done.
No sound yet. Checking alsamixer channels.
All unmutted and at max. No sound.
Trying alsaconf:
# [EMAIL PROTECTED]:~$ sudo alsaconf
# Unloading ALSA sound driver modules: snd-hda-intel snd-pcm snd-seq
snd-timer snd-seq-device snd-page-alloc.
# Building card database...
# Loading driver...
# Setting default volumes...
# Now ALSA is ready to use.
# For adjustment of volumes, use your favorite mixer.
# Have a lot of fun!
SOUND!
[...]
Run "lsof $(find /dev/ -group audio)" to see if there are any
applications or sound daemons blocking the sound devices.
This command returns nothing just after system boot.
Only after alsaconf I can hear the 'speaker-test' sound.
Please post the output of the following commands (before you run
alsaconf):
cat /dev/sndstat
[EMAIL PROTECTED]:~$ cat /dev/sndstat

There's a lot of "NOT ENABLED IN CONFIG" in this output. I guess this
might mean something.

It would furthermore be interesting to know if the output of the last
one (the module parameters) changes after you run alsaconf.
There's no difference between both outputs as well.
Hope we can figure out somehting.
Thanks again!
Vinicius
