Good to find I'm not alone. The microphone works fine - the person on the receiving end can hear what the pinephone says just fine.

Sound a little nuts, but this is how I solved it..
1) Turn off the phone
2) Turn switch 6 from headphone (ON position) to UART (OFF position)
3) Turn it back on.
4) The phone should make calls then without the distortion in the audio received.
The phone seems to work without call audio distortion as long as UART mode is enabled (headphone disabled)
To get the phone to work while switch 6 is in headphone mode.. This is weird ..
1) Get a pair of headphones.. plug in
2) Try inserting a headphone in and out of the jack a bunch of times...!
3) Do a sound test from systems system sound test from settings.. swap the output device to headphone. You should hear it (left/right is reversed at the moment.)
4) Set the call audio to the headphone.
5) Make a call.. Hopefully you can hear it though the headphone! (If not power off, remove battery, swap to UART mode again, verify it works in call with earpiece, power off remove battery, then try again with headphone test)
6) If the headphone is working in a call (it might be low volume, or you might only hear one headphone!) Then unplug the headphone and set the audio to earpeice.. Now for some reason the phone is working without the distrortion, and atleast mine continued to do so the 2nd time I did this. Even after having battery removed.
