Failure to switch to AAC on Sony WH-1000XM4 Bluetooth headphones
Running Fedora 33, Linux 5.10.12, bluez 5.55, pipewire 0.3.21, with KDE Plasma. The WH-1000XM4 works well with LDAC and SBC, but when I try to switch to AAC, then I get
pipewire-media-session: bluez5-device: failed to switch codec (-19), setting fallback profile. Then, since it's the fallback profile, the Pulse-based (?) KDE settings will only show HSP/HFP until we reconnect Bluetooth (at which point LDAC or SBC, whichever works, will work perfectly fine until we try to change to AAC again). All the FDK-related packages are installed, of course.
