Headphone jack audio bugs, during phone calls

When making phone calls sound can only be heard out of the left earphone, and the microphone of a TRRS headphone+mic set does not function, only the internal microphone is used.

All other sound output seems ok, volume up & down sounds are coming out of both earpieces, as well as listening to web browser multimedia content.

Possibly same bug is present in Phosh also, only confirmed with one other person.
