 OK, so far, I've figured out that the dissapearing sound isn't caused by
 "dropping amount of vchans". I am not entirely sure how did
 hw.snd.pcm0.vchans get dropped to 1 "by itself" as I mentioned in
 my previous mail, but this doesn't seem to be happening now. However
 whenever the sound dissapears, I can consistently get it back in 1-2
 tries by bumping vchans down to 0 or 1, waiting a few seconds and
 changing their amount back to 4 using sysctl. It's nice to have a
 workaround for this problem, but I'd also like to know the real cause
 and have a permanent fix for the problem.
 
 Sincerely,
