For what it's worth I got a pine phone pro delivered this past week and have had the following experience with respect to audio and calling:
The stock OS has no sound in calls. Perhaps I did not set it up correctly.
I tried the Manjaro-Phosh image from 11/10. Sound on calls did not work. Perhaps I did not set it up correctly.
I tried the recent mobian (11/06 image). Sound on calls worked once, then did not. But since doing an
# apt-get update && apt-get upgrade
sound has worked, though with poor quality going out from the pine phone, on calls for the couple of trials I have done over the last day, including incoming calls from suspend.
