cannot get a2dp profile enabled

Hello,

I hope this is the place to ask for user questions, bluez.org offers no
other mailing list....

I have a Jabra headphone/headset device and pulseaudio can´t activate
the a2dp_sink, I want to be sure, A2DP is properly enabled in bluez.

bluetoothctl info MAC-OF-HEADPHONE says:

UUID: Advanced Audio Distribu.. (0000110d-0000-1000-8000-00805f9b34fb)

Thus, the device supports a2dp.

At the bottom I put output from "show CONTROLLER-MAC".

I tried

register-service 0000110d-0000-1000-8000-00805f9b34fb

to no avail, still no a2dp_sink in pulseaudio.

How can I ensure using bluetoothctl that a2dp is really enabled in bluez?

I´m not sure, if I deal with a bluetooth or pulseaudio issue, I want to
exclude a misconfigured bt device.

I´m using bluez 5.48 and kernel 5.11.3.

Thank you very much in advance!
