Hello,
(apologies for a long post, but I thought it would be best to
include as much relevant information as I could)
I'm trying to install Alsa on my system, but alsamixer returns
the error message:
alsamixer: function snd_ctl_open failed for default: No such device
System:
Via Epia M1 mainboard with on-board audio (via-82xx)
Debian 'testing' distribution
Kernel 2.6.6, custom compiled with special Epia patches
Only text-based, no X installed.
The program 'aumix' is working correctly, also I can play MP3
using mpg321. It just doesn't feel right that alsamixer doesn't work.
I have found a lot of messages from other people with the
same problem, some solutions but they didn't work for me.
For example, running the script snddevices in the Alsa
source directory didn't help.

The two modules above are OSS modules, you have to remove them.
