[alsa-devel] routing audio stream to multiple devices

[Emilio López]

I don't really know how to do this on dmix, nor I do know much about
alsa or dmix. But I'm quite certain this is achieveable with
pulseaudio; I have done it once using the GUI they provide.

Might be of help if you still want to use dmix:
