Microphone not working on Pinebook Pro

[vfr400racer]

I recently discovered that my microphones are not working. I'm on manjaro testing. Has anyone a working microphone on the Pinebook Pro? If so, which distro are you using?
regards,
Hans-Peter

Im on Manjaro-ARM kde:5.21.1, kernel:5.7.19

I am having the same issue. I followed the instructions here:
https://wiki.pine64.org/index.php/Pinebook_Pro
Went so far as to taking it apart. I traced to the wiring to the taped holes.

Currently it is not showing up on pavucontrol nor elsewhere.

Help!?

Thanks in advance!

 I tried another image. I can't remember, if it was mrfixit's or ayufan's image. I got microphone input with that. So it's not the hardware in my case. Seems as if Manjaro is missing microphone support .
