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 :)

It seems that it's time to write some debugging tool which dumps registers of running card using iopl().

Power-management? How would that affect the sound driver? I thought you were talking about APIC - the extended interrupts. In any event, I have power management disabled and I have tried it with both APIC interrupts and without. I'm still failry skeptical about it being a hardware problem because I can: 1) load commercial OSS drivers -> works 2) unload commercial drivers 3) load ALSA drivers-> does not work, strange error messages 4) Reload commercial OSS driver -> works So, without rebooting (so no change in interrupt allocation, io base whatever else) one set of drivers works and the other does not. BTW OSS/Free drivers also do not work. What I don't know is how to go about troubleshooting why the ALSA driver seems to not work?

this might be related with a hardware set-up.
try to play around with ACPI, etc.

[Alsa-user] Asus A7V8X-X (via8233) no sound
I'm still trying to get ALSA working with the onboard sound on
my ASUS A7V8X-X MB. The lspci command shows the audio controller as
being a VT8233 AC97 Audio Controller. I'm using RedHat9 but with kernel
2.4.21-rc5. I am also using ALSA 0.9.4. The driver builds OK and the
only indication I get that something might be wrong is the following
error message when I load snd-via82xx:
ALSA ../alsa-kernel/pci/via82xx.c:503: codec_valid: codec 0 is no valid
[0xfe]
The symptom is basically no sound - I'm using mpg321 to play an
MP3 file. I know I've got ALSA working in general since I also have a
SoundBlaster PCI-64 (I think that is the name) and I build the ALSA
driver snd-ens1371. When I load this driver and set the mixed settings,
I get sound from the SB. So, I know I'm building the drivers correctly
and getting the mixer settings right etc, I'm just not getting any sound
with the onboard controller. Oddly, when I try to build ALSA with
--with-debug=full I get some strange unresolved symbol errors:
"unresolved symbol _snd_magic_kcalloc_R{something}"
So, my first question is - what does the error message about
invalid codecs mean? And secondly, does anyone else have ALSA working
with RH9 and an ASUS A7V8X-X?
Many thanks,
-poul
