[Alsa-user] playing / recording mono on a stereo-only hardware

[Guennadi L. <g.l...@gm...>]

Hi

I'm writing a driver for an embedded system (SuperH, first version of 
patches posted recently on alsa-devel), and the driver claims support for 
only 2 channels (channels_min = channels_max = 2). Is there a way to tell 
alsa-lib to duplicate the mono-channel during playback and to mix recorded 
channels, if mono recording is requested?

Thanks
Guennadi
