[alsa-devel] get two mono channel from stereo line

[arif setiawan]

Thank you.
It works as we expected, however we found that we can't run two lines
(left-capture - left-playback) and (right-capture - right-playback)
simulatenously.

The error message is :
ALSA lib pcm_dshare.c:706:(snd_pcm_dshare_open) unable to open slave
cannot open output audio device right: Device or resource busy

Is there any workaround for this?
