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?
I'm not an expert but I think that you can use plughw support of alsa-lib
pcm.record { type plug slave { pcm record_hw } route_policy average rate_converter "linear" }
I think that automatically change rate and channel for supporting mono channel too
Thanks for the snippet, but, I'm afraid, it didn't help either.
Sorry can you explain a little bit more why it doesn't help you?
I certainly gladly would explain this, if only I knew... It just doesn't change anything. Are you using it anywhere? If yes, with which hardware configuration and software (alsa-lib) versions?
alsa-lib 1.0.16
#define BUILD_PCM_PLUGIN_RATE "1" #define BUILD_PCM_PLUGIN_ROUTE "1"
