Summary:                    [patch] Asterisk ALSA interface consumes physical
input and output regardless of whether or not they are needed...
Description: 
I have hacked on chan_alsa.c (attached) to allow either ALSA input or
ALSA output or both to be specified.  Previously, Asterisk would
consume a physical ALSA input and physical ALSA output whether it was
going to make use of them or not.  This is problematic when one wants
to make use of a cheap analog microphone to interface to applications
other than Asterisk and there is only one analog input on the
motherboard.  Asterisk would consume the input and it would not be
available for any other application.  Again, this is a hack and
comments and a more elegant solution are desired.

I honestly don't see the benefit of this.  It brings about a whole bunch of
ways for things to break.

Having said that..  ALSA has done mixing for several years now.  If you
use "default" as the device names, it should not block providing you have a
sane ALSA configuration.
