I don't think that you need to have /proc/asound/sndstat. I have a VIA
VT82C686 AC97 audio controller (which uses the same driver module as
your card) and it works without /proc/asound/sndstat existing.

All the information that you posted suggests that your card is properly
recognized and should work. How did you test the card? The easiest thing
is to run "speaker-test" from the command line and watch for error
messages.
If you do not get any error messages but you still do not hear any
sound, then you have to check the volume settings. Run "alsamixer" and
make sure that the channels "Master", "Master M" and "PCM" are unmuted
(no "MM" visible; you can toggle this with the "m" key). Try to turn up
the volume with the cursor keys (left/right to select a channel and
up/down to change its volume) and see if that helps. (Press ESC to exit
alsamixer.)
