[alsa-devel] Query - ASoC headphone detection stereo vs. mono

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?
