Hello, Igor Kovalenko solution work for me only if libspa-0.2-bluetooth package is installed.
The solution is described in https://wiki.debian.org/PipeWire#Bluetooth 1) Only pulseaudio-module-bluetooth is installed; it is impossible to pair. 2) Both pulseaudio-module-bluetooth and libspa-0.2-bluetooth are installed; pairing is flaky but not impossible. (Few failed attempts before success.) 3) Only libspa-0.2-bluetooth is installed, pairing is reliable. (It failed the first time after pulseaudio-module-bluetooth was removed.) Failure always end in src/service.c:btd_service_connect() a2dp-sink profile connect failed for XX:XX:XX:XX:XX:XX: Protocol not available message. Best regards, Sincerely, Viktor Malyarchuk
