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.
But, 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. So:
-Any ideas on how to get alsamixer to work? -is there an alternative to alsamixer to unmute?
Lastly, if I have a kernel compiled as indicated above, I'm unclear if I
*need* to install alsa-driver, alsa-liband alsa-utils ..... but in any case I
tried to install alsa-lib-1.0.2, and the make fails with:
