I think the following should do something like that: arecord -Dplughw:0.0 | aplay -Dplughw:0.1 or arecord -Dhw:0.0 | aplay -Dhw:0.1 I don't know what is the order of the PCMs with the twl4030 codec on your board, this is with the assumption: plughw:0.0 - Voice PCM (McBSP3) plughw:0.1 - Digital audio PCM (McBSP2) You might want to try the --rate parameter for arecord to use 16KHz recording from the Voice interface.. > > Regards, > Shariff > _______________________________________________ > Alsa-devel mailing list > Alsa-devel@xxxxxxxxxxxxxxxx > http://mailman.alsa-project.org/mailman/listinfo/alsa-devel -- Péter _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
