BP50 problem

can someone help me ?
I recently bought bp50, and I can’t connect the headphones/speakers
I open the application, connect to the device, after which I press line in, it sees the headphones or speakers, but I don’t hear anything…
Thank you !

Please check the volume settings, if it connects, it should be supposed to be working.

I have a similar problem with my headphones.
The BT connection is active, but no sound is output from the headphones.
In this case, the sound output via the connected speakers is deactivated.
Volume is at approx. 80%.
Is there anything else that needs to be adjusted?
