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.
