Pinephone Pro Earpiece is not working, need help
#1
Some time ago I noticed that I no longer hear my peer during a call. After some investigation and trying different images I installed factory test image from here: https://wiki.pine64.org/wiki/PinePhone_P...e_Checking
No sound can be heard during earpiece test even there . So I come to conclusion that Earpiece is not working on my device at all. It was working previously, sadly I cannot confirm exact point when the issue started.
Is there anything I can do with that?

I am not sure does this help but for me some things cause issues with earpiece audio:
These all might be coinsidents so take them as they are (some stranger from the internet is just telling you something Big Grin )
- When my wifi/bluetooth killswitch was off it somehow cause pulseaudio suspending really fast
- Newer kernels cause audio issues for me on Mobian, PMOS and Manjaro
- Before I upgraded Tow-Boot to latest version audio was not that reliably functioning (no idea what my Tow-boot version was but I received my PPP like three weeks ago)
- If I suspend as root it will cause audio issues (for example with sleepwalk scripts or similar)

Hope you will get working audio back Smile

If the factory test image also does not work, you might also have a faulty part.

Measure the resistance between the pins. If there is no connection, it's dead.

I created a thread for this exact issue, that I just fixed today: https://forum.pine64.org/showthread.php?tid=18075
