Definitely sounds like software given you have tested every possible scenario and the results are all over and not predictable.
Possible an issue with pulse/alsa and hot plug detection.
Very weird.

OK, so just to update future readers of the thread.. I had an up to date PMOS on my handset until today still with call audio issues (low volume, robot voice, cant understand - all sporadic, and recurring. yes flicking switches like a wildman sometimes solved it. however ..)
I put Mobian on the phone a day or two ago and been testing.. Call audio worked right away and after apt-get update and dist-uprade and most of the other stuff works as well such as bluetooth (not mic) and power saving. Works like a regular phone handset now which is a relief..
It really must be drivers/config issues with PMOS.
Not to take anything away from PMOS but if you are suffering with a handset that doesnt make calls try Mobian until PMOS gets a bit further along..
