The problem

Steps to reproduce

WhatsApp calls or video calls are mute just for me, the other part can hear me, but i can't hear anything back. I used the previous GSI rom version and this was okay, but i dropped it since it was all buggy, bluetooth wouldn't work and was not mantained, but the last version from April carries this WhatsApp problem.

Speaker and Mic is working fine everywhere else.

Technical informations

Relevant logs (adb logcat)

The only log i have is the one i did with the Developer Options function, but i really am not an expert in this, i can't read logs, i just do it because in previous issues i have, people have told me to do that. So i'm attaching it.
