ah.  i think this was the missing piece, for me -- that while only
one program can have the pcm device open, more than one can have the
mixer open.

do you think it even needs to be configurable?  any reason not to
just leave the mixer open all the time (assuming we're not configured
to never use it at all)?  if configurable, it seems like it should
be a boolean, separate from the mixerinit options being discussed.

btw, i think i like the idea of having finer-grained boolean options,
rather than a large set of mixerinit values.  but you two have a idea
of how that should work, so i'll leave that up to you.
