I just tried to use wireplumber instead of pipewire-media-session. Sound working flawlessly, but bluetooth is not working. Service is up and running, no block (neither hard nor soft), but no adapter available. Going back to pipewire-media-session, solves the problem. As I’m in hospital right now and just had my surgery yesterday, I’m not in the mood to figure out, what the problem is. I’ll have a closer look, when I’m back home.
