I am facing issues on my Pixel 8 (running Graphen OS, Android 14).
The bluetooth connects fine to the Sony WH-1000XM4 headphones and listening works perfectly.
However, the microphone of the headphones are not used, the build-in microphone is used instead.
The headphones works as intended on stock Android.
I have the same issue with wired USB-C headphones
and also for wired headphones with a jack and an adapter.
For all headphones, listening works fine, but the build-in mic is used instead of the external mic.
The problem occurs on the main as well as the secondary profile.
Mic permission is granted and I tried the different device-type options (e.g. headphones, headset) in the bluetooth device setting.
Does anyone know what is going on?
