I have a Biostar system with Athlon board, VT8237 southbridge (includes audio) and C-Media CMI9739A AC97 Codec. The system has SuSE 8.1, but with custom 2.6.2 kernel. I compiled the kernel with soundcore and snd_via82xx as modules, updated /etc/modprobe.conf, and the modules seem to load correctly (see below).
I have fixed earlier problems I had with libraries and header files, and have now installed alsa-lib and alsa-utils successfully.
Still, no sound. I understand ALSA starts muted, so I tried alsamixer.
When invoked, it just hangs. Curiously, when I do strace alsamixer,
it "sort of" gets to the mixer display - the display is somewhat garbled, and totally unuseable.
I then tried to set volumes with amixer, and now I have the settings below. Still - no sound - either in trying to play test.wav, or in
trying to play a cd with gnome-cd. I had previously tried to set this
machine with the viaudiocombo OSS driver - that didn't work either,
but gnome-cd *did* work at that point.
Ideas appreciated.
Thx, Randy
