Hugo

Having 'device pcm' in the kernel is all you should need for you VT82C686 
(kldload'ing sound drivers requires pcm support not be compiled into the 
kernel.

The are two portions to the sound h/w you have, the pcm component, ie the 
VT82C686, and the AC97 codec that controls the mixer and routing of the audio 
within the h/w.  The AC97 code does not detect your AC97 codec so you end up 
with a pcm component with no ac97 mixer.

Does you BIOS have an onboard sound setting?  If this is not enabled then 
might explain what you see.  Failing that can you post the complete output of 
dmesg and set 'sysctl hw.snd.verbose=3' and post the output of 'cat 
'/dev/sndstat'?

Thanks
