I would like to get a better understanding on how to propagate channel mode of inserted headphone through soc-jack framework? 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?
The Jack detect core doesn't have this sort of functionality yet. We can report insertions and device type (if supported by the hardware) but it does sound like we need to additionally pass this sort of information up if required.
Another agenda topic.
Thanks
