[alsa-devel] Application and hw mixing for VoIP (modified)

[Fabien COMTE]

Hi,
I need some help please.
I have an application that does VoIP and alsa interface.

I want to :
- send through VoIP application a mixed sound from mic and an another
application (aplay should be ok for testing).

mic ---------- soundcard 0 ------------->
                                           mix  ---- alsa interface ----->
voip application
application 1 --- alsa interface  ------>
(aplay)

- use sound received from VoIP with HP output and an another application
(arecord should be ok for testing).

                                                   ----- alsa interface
------> application 2 (arecord)
voip application ----- alsa interface ---->  share
                                                   ------ soundcard 0
--------> HP output


And a little question :
How to define an application interface in asoundrc ?
	

I tried a lot of asoundrc but they doesn't work.

Could someone help me ?
Thank you.
