Bluetooth headphones no sound

[newbee90]

Finally I have managed to pair my bluetooth Teufel headphone to raudio, but I have no audio on my headphone. I see the bluetooth sign in the left circle. Sound comes always on 3,5 output, I can decrease and increase the volume but but it does not change the volume on 3,5 output. So I think raudio is connected to my headphone but I can't hear anything

Please check mixer device in Player settings.

what do I have to change? After a while it disconnects my phones

I would start with disabling Device+Bluetooth. You do not need this for bt phones.

[newbee90]

thank you, but nothing has changed. Still sound per 3.5 output and no sound on my phones.

Now, forget the bt pairing and connect phones again.

no change


I can connect my mobile phone th Raudio and I can play music to Raudio but it sounds like an old scratched CD, so there must be a software or hardware issue. I use a raspberry 4
