ADDITIONAL INFORMATION:

I attached some screenshots also. I also tried to pair via Bluetooth to FiiO M15S DAC/DAP it connects once paired via Bluetooth and put the DAC into Bluetooth Receiving mode and connects via SBC codec, but no sound no matter if native music app or streaming and no matter which options I choose in the Audio Output either.

I tested with different audio cables and also with my Google Pixel 7 Pro with GrapheneOS and works fine either way.
