OK :) same thing for me basically, I'm not that techo...

Tried that, with hw.snd.maxautovchans as well as with hw.snd.pcm0.vchans. 
Didn't work. With both on 0 every FreeBSD binary behaves fine.

On the soundsystem: what exactly is the difference between say dsp0.0 and 
dsp0.1? (No, changing settings in Linux progs to these devices doesn't work. 
It still appears to look for /dev/dsp)

Other ideas?
