Bluetooth device not visible to pipewire?

Hi list,

I am trying to see or set a bluetooth audio device in either pavucontrol
nor qpwgraph on Debian stable.

The bluetooth speaker is connected and I am able to play back via
	aplay -d bluealsa somesound.wav

however it is not visible to pipewire, as
	wpctl status
does not report any bluetooth audio device.

Installing libspa-0.2-bluetooth did not help.

Some web forum page suggests creating /etc/bluetooth/audio.conf with
contents:
	[General]
	Enable=Control,Gateway,Headset,Media,Sink,Socket,Source
which I haven't tried yet.

Is there anything I could be missing?

Thanks!
Peter
