#1 match options to mixer

[Bryce Nesbitt]

Aumix offers a bunch of options for which mixer
channels to
affect:
-c CD
-l line in
-x imix

But I use a number of weirder mixers (USB mostly) that
have different options. This is either a question or a
bug report or a feature request.:

I'd like to run "aumix -q" to list all the mixer
channels by name, then adjust them by the same name.
E.g.:

aumix -q

vol 64,64
dgain 64,64

aumix -c 'dgain' 32

I don't think that making aumix handle multiple mixers
is much a priority, but making sure it can adapt to any
mixer is.
