Hi all the comments about how to activate pipewire are somehow strange to me, I guess because you followed some ubuntu guide.
BUT indeed, libspa-0.2-bluetooth is necessary for bluetooth audio compatibility. Just retried it and after installation and restart of pipewire I could connect my BT headphones. I think "someone" should recommend libspa-0.2-bluetooth, maybe pipewire itself.
