|Summary:||ASTERISK-13329: [patch] Asterisk ALSA interface consumes physical input and output regardless of whether or not they are needed...|

( 1) unified_diff_with_tip
( 2) unified_diff_with_tip2
|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 signed up for a license, how come I do not have one yet?
By: Leif Madsen (lmadsen) 2009-06-15 16:43:03
The reason is because the status messages are set manually by a bug marshal (primarily me) and I hadn't noticed that your license was approved. I have set this issue back to the appropriate status. Thanks!

It looks like you've attached the entire chan_alsa.c file, where really you just need to attach your changes as a unified diff. Thanks!

I just attached a file called "unified_diff_with_tip". I did and 'svn update' followed by an 'svn diff > unified_diff_with_tip'. I hope this is what you need.

Yes this looks much better, thanks! Marking this as Ready for Testing. If you can, please post to the asterisk-dev list to try and coax some people into testing this out :) Thanks!

This code looks like it was written for 1.2, not 1.4, and it really should be against trunk.

Suspended due to lack of activity. Please request a bug marshal in #asterisk-bugs on the IRC network irc.freenode.net to reopen the issue should you have the additional information requested.

This code is from 1.4.25 no 1.2. I fail to see why this was closed. The code is directly from the 1.4.25 source tarball.

The code still needs to be against trunk.

It is against the trunk...see my last note. I uploaded a new "diff" file... ;-)

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.
