No sound - onboard VIA VT8233 AC97

[Josh Metzler <joshdeb@metzlers.org>]

I would appreciate any advice anyone can give me as to how to get sound 
working on my new box.

The mother board is the Shuttle AV49N, which has onboard VIA VT8233 AC97 
sound.

I have been testing with cat reflect.au > /dev/dsp.  (reflect.au is a sound 
that comes with kbounce.) This returns with no messages, but also with no 
sound coming out the speakers.

Thanks in advance,
Josh
