OK then it sounds like we just need a diff -u of the cpcap regs from Android with cpcaprw --all before and after using a bluetooth headset during a voice call to configure it for voice calls for the TDM. I think snd-soc-motmd just needs the voice output specified in the mixer in addition to the cpcap configuration.
I don't think have any bluetooth audio gear though, maybe somebody using a headset can post the diff.
