Very interesting.  You just solved a puzzle for me.  I tried compiling
the 'pcm' device into my custom kernel -- which never worked!  I always
had to load the via8233 module manually at boot, and now I know why.
(My SWAG would be that this is more buggish than featurish.)

Just as a minor aside, loading the via module will automatically pull in
the snd_pcm module, so you needn't load it explicitly.  As a more major
aside, I do not load the snd module at all, and yet my sound works fine.

Can you try loading only the snd_via8233.ko from loader.conf and see if
you get satisfactory sound?  What other modules get loaded when you try
this?

Thanks.
