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.

Fabien
