A2DP Hardware vol not working on Bose Mini Soundlink II, but does work with android, and with HFP profile
Connecting my bluetooth speaker to my android phone the hardware volume buttons change the phone volume slider using an A2DP/SBC connection. AVRCP on phone is 1.6.
Connecting to pipewire-git (built 6th May) hardware volume works using HFP profile, but not using A2DP profile.
