I forgot to ask: what mode you are using the McBSP? Is it in element, or threshold mode? You can check/change the McBSP mode in: /sys/devices/platform/omap-mcbsp.2/dma_op_mode
It is in threshold mode, with max threshold 1023. I will try other modes.
For playing, the left and right are the same data, we could not
tell if
the channel switch happens to playback as well.
I see. Is there a way for you to run your application to capture only, and from a separate app (aplay?) play a sample, which has audio only
on
one channel?
I can fill zero to one of the play channel in our app to test it.
Thanks, Ying
