I have two sound cards, one attached to pc speakers and one attached to a sound system in another room.
Following instructions on the alsa project wiki, I am trying to use two sound cards (V8237 and CA0106).
I configure my ~/.asoundc but I still can't manage to send a sound to both cards at the same time. Below is my ~/.asoundrc content.
When I tested directly the ca0106 card (hw:0,0) with a play, it didn't work so I thought it might be some sort of rate or conversion problem. I added the pcm.via and pcm.audigy in my asoundrc file and then, when I test each card individually ("via" and "audigy") with aplay it works well.
When testing the "multi" pcm with aplay ( aplay -vD multi question.wav ), I get the following error
aplay: set_params:959: Nombre de canaux non disponible (Channels count non available)
Any help or suggestions are welcome
