Your standard LM8.1 kernel is OK, don't worry ;)

What does 'cat /proc/asound/cards' report? Do you use devfs (it's standard
in LM8.1) ? You unmute channels with a mixer but your problem is the mixer
complains about /dev/mixer. When I boot with devfs I get this:
[frans@amd frans]$ ls -l /dev/mixer
lr-xr-xr-x 1 root root 11 Nov 21 18:29 /dev/mixer -> sound/mixer
[frans@amd frans]$ ls -l /dev/sound/mixer
crw------- 1 frans audio 14, 0 Jan 1 1970 /dev/sound/mixer
[frans@amd frans]$
Btw, I normally boot without devfs (there was some security issue IIRC) and
sound then also works well. Anyway, I think the ALSA driver loads OK, OSS
emulation is set up correctly, but there can be problems with using/not using
devfs, permissions, the use of a sound daemon like esd ... I can only wish
you the best :)

I read a post in french (!) on the alsa-user list (!) recently from someone
who lost sound after his 'upgrade' to Windows XP ....
