[alsa-devel] routing audio stream to multiple devices

[Baek Chang]

I'm trying to acheive this with dmix and alsa.  I know that pulseaudio can
do this, but we are getting rid of pulseaudio on our embedded system and I
am trying to find a solution with alsa.  I'll take a look at the dmix docs,
thanks!
