We're happy to try to help. I have a friend with your model of 
laptop, I'll see if I can sucker him into letting me futz around 
with it for a day or two. I'll report back!

Not entirely sure what one would glean from /proc other than that 
the card is present and drivers are loaded for it. There's lengthy 
output for my sound device. I won't paste all of it, but everything 
is located in /proc/asound. My device is also listed under 
/proc/devices as one would expect.

I don't muck in /proc very often other than for testing network 
setups and obtaining cpu and memory information, so the output for 
my soundcard means next to nothing to me other than I know the 
correct driver is loaded.

[prata at crane asound]$ ls
card0  cards  devices  modules  oss  pcm  seq  timers  V8237  version

[prata at crane asound]$ pwd && cat modules && cat cards
  0 snd_via82xx
  0 [V8237          ]: VIA8237 - VIA 8237
                       VIA 8237 with ALC850 at 0xe800, irq 209

Given that your machine is reporting the device as present (despite 
not getting any sound) I am under the impression anything you get 
out of proc would be correct as well. Just to through more confusion 
on the issue. ^_^

I don't know why I never googled around on the Alsa lists. That was 
stupid of me. Opensuse has some forums with this problem as well. I 
didn't see a fix, but I didn't spend too much time looking there. If 
there is a fix, maybe they have an srpm that could be massaged into 
working in CentOS?

If you do find a solution elsewhere I'd really appreciate a link or 
something just for my own knowledge down the road.
