Did you run "alsaconf" already? (It is easy to miss things with all this
top-posting. It would be better if you put your answers and reactions
below the questions that prompt them; this results in a chronological
"story" and makes it easier for other people to join the discussion.)

Then maybe we should check if your sound devices are created at all in
/dev and if they have the right permissions. You can run this command
and compare the output:
$ find /dev -group audio 2>/dev/null | xargs ls -l
crw-rw---- 1 root audio 14, 4 2006-06-16 12:25 /dev/audio
crw-rw---- 1 root audio 14, 3 2006-06-16 12:25 /dev/dsp
crw-rw---- 1 root audio 14, 0 2006-06-16 12:25 /dev/mixer
crw-rw---- 1 root audio 10, 135 2006-06-16 12:25 /dev/rtc
crw-rw---- 1 root audio 14, 1 2006-06-16 12:25 /dev/sequencer
crw-rw---- 1 root audio 14, 8 2006-06-16 12:25 /dev/sequencer2
crw-rw---- 1 root audio 116, 0 2006-06-16 12:25 /dev/snd/controlC0
crw-rw---- 1 root audio 116, 24 2006-06-16 12:25 /dev/snd/pcmC0D0c
crw-rw---- 1 root audio 116, 16 2006-06-16 12:25 /dev/snd/pcmC0D0p
crw-rw---- 1 root audio 116, 1 2006-06-16 12:25 /dev/snd/seq
crw-rw---- 1 root audio 116, 33 2006-06-16 12:25 /dev/snd/timer
(I have a different sound card, therefore your output does not have to
be 100% identical.)
If your card is recognized it should also show up in /proc/asound/cards:
$ cat /proc/asound/cards
0 [rev50 ]: VIA686A - VIA 82C686A/B rev50
VIA 82C686A/B rev50 with ICE1232 at 0xdc00, irq 5
> Finally, are the modules with 'oss' in the name alsa modules?
The names of the alsa modules all start with "snd_"; if the name ends
with "_oss" then it is an alsa module that provides a compatibility
layer for applications which still use the old OSS interface to access
the audio hardware.
