Awesome!  Cloning works, the volume-going-down-with-each-open(2) problem
is gone.

I do get some audible artifacts with this patch, though, at least for
mp3 playback using mpg123 (will poke at it in more depth later).  Hard
to explain, but something like a periodic (every 2-3 seconds), white
noise stutter intermixed with the playing track.  Sounds like buffer skip(?).

My audio chip being
hdafg1 at hdaudio1: vendor 1106 product 0397
audio0 at hdafg1: full duplex, playback, capture, mmap, independent

In any case, thanks for implementing this!
