Hi I know this question belongs rather to alsa-users, and I did ask it there, but got no solution so far. Maybe someone here can help. The recently posted SuperH SIU driver only supports stereo playback and capture (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 (or use one of them), if mono recording is requested?
