  Modified files:
    sys/dev/sound/pcm    vchan.c 
  Log:
  - Increase snddev refcount earlier while accessing through sysctl interface
    to avoid possible device unregister race (impossible to reproduce, yet
    possible).
  - Extra sanity check to ensure proper parent channel is being selected.
  - Reset parent channel once all of its children gone.
