I think it's the cpcap based config to route voice call audio to SoC, Sebastian knows the details :) The way to figure that one out is to dump the cpcap registers before and during voice call on android with cpcaprw, then diff the output for the audio registers. Probably some SoC registers need to be diffed too with rwmem or similar tool for the mcbsp instance(s) used.
