Hello,
please try using something like that. (un-tested). Playing to dev1 and dev2
should then create mono streams with are send to one of the dmixer channel.
Check http://www.alsa-project.org/main/index.php/Asoundrc to see what is going
on.
Regards,
Mathias

Hello,
yes, check a combination of "dmix" and "route" (or plug) to do that:

Hello, I want to use the channels of the usb audio codec with independent
sounds. Is it possible to make these channels separate devices by using alsa
plugins?
