Creating independent I/O devices from left and right channels

Former Member
Former Member over 10 years ago

Hi,

 

I am trying to use two microphones and two speakers connected to the cirrus card that will need to be used by different applications (i.e. one application using left channel of the mic/speaker and another application using the right channel of the mic/speaker).

 

I have tried creating ALSA slave devices (in .asoundrc) to demultiplex the left and right input/output channels from the audio card but haven't had any success.

 

Is what I'm trying achieve possible with the audio card? And is it possible to achieve using ALSA configs or will I have to dig down to driver level?

 

Thanks,

 

Ben
