Ahem. Well, I figured out the problem and it was PEBKAC (Problem
Exists Between Keyboard And Chair). So, here is the deal with the
snd-via82xx driver on my platform:
1) The "master" and "master mono" volume controls do nothing
2) The "surround" channel had to be unmuted.
Yes, that's right, the "surround" channel was muted and it was
changing this that made sound "magically" start coming from my on-board
sound. Yes, I feel pretty stupid for not thinking of this sooner,
considering the hours I have spent trying to figure out what was wrong.
On a second note, the sound was plain awful for the MP3 playback
I tried; there was a nasty high pitched noise noticeable on high
frequency sounds. I switched over to using /dev/adsp as suggested
and the noise went away. Now it sounds great!
Thanks everyone for putting up with my posts :)
