I looked at jack.h and I don't see any definition of channel mode. I would assume that user-space needs this information in order to set up the path in the audio CODEC properly such as mixing stereo content into mono stream inside CODEC. How is use case handled on other platform? Thanks Patrick -- Sent by an employee of the Qualcomm Innovation Center, Inc. The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum.
