The sound card is probably not able to handle two independent mono
streams, but it is possible to use alsa-lib's software plugins to
emulate two devices on top of the real one.
Put this into your ~/.asoundrc or into /etc/asound.conf:
pcm_slave.stereo_slave {
pcm "hw:0" # or "hw:1" for the second card ...
channels 2
}
pcm.left {
type plug
slave.pcm {
type dshare
slave stereo_slave
}
bindings [ 0 ]
}
pcm.right {
type plug
slave.pcm { type dshare slave stereo_slave }
bindings [ 1 ]
}
Then use device names "left" and "right" instead of "default".
