c2450501af Prefer mixer controls with volumes over switches 
When we look for a mixer control prefer controls that have both volume
and a mute switch over those that have only a volume switch over those
that only have a mute switch.

Originally pointed out by Adel Gadllah.

3d07cc8112 alsa_error_handler should note source of errors 
When an error gets passed up from alsa-lib via alsa_error_handler, it's unclear
the source of the error. alsa_error_handler should note that the error came
from alsa-lib. (Closes #341)
