bluetooth volume not controllable

[belafonte]

Hello hello,

just installed everything from the script.
So far everything works well.

The only thing that does not work is controlling the volume via bluetooth.
I'am using a usb bluetooth dongle and disabled the internal bluetooth module via: dtoverlay=pi3-disable-bt.
Not sure if that is correct though.

Any ideas how to solve this?

edit: and just out of curiosity, would it be possible somehow to output the audio as mono, when it is transmitted via bluetooth?

Try disabling Bluetooth using this more recent guide:
