Hello,

I was peeking in the NetBSD audio driver sources (spying for Linux/m68k :-))
and I think I found a bug in audio_open():
At the end of this function, the channels used by the unit are marked as
busy by setting
    channel_busy[ch] = unit;
But 'unit' can be 0, this means that channels used by unit 0 are never
marked as used, and unit 0 can be opened simultaneously be several 
processes, thrashing each others sound data (theoretically, can't test it)..

Regards,
Ingo
