I have a Pixel 5a running GrapheneOS on Android 13.
I recently bought an external microphone to use with the phone. It connects via USB-C, a Boya BY-M3. It works with the phone but the input volume is far too high.
Steps I have taken to resolve:
- Restarted phone (did not change anything)
- Tested the microphone on my laptop (normal mic volume on laptop)
- Tried several different audio recording and camera/video apps, including ones where you can adjust recording volume (no change)
As it didn't change no matter which app I used, I'm beginning to suspect it's either an issue with my phone (unlikely as it's only a few months old, brand new) or something with GrapheneOS. I've tried to find somewhere to adjust the microphone input volume but I can't find one.
Any tips or suggestions on how to resolve?
