This thread got me curious about Bluetooth on Pipewire. Using a pair of Soundcore Spirit X headphones, I paired them in Fedora 35's Gnome bluetooth settings page. Then tested and it worked great. I even changed the audio codec from SBC to SBC-XQ and it still worked after disconnecting and reconnecting (which it did automatically)

Very impressed!

My issue with bluetooth audio on linux is when playing games or other application that max out the cpu, the bluetooth process can be starved of cpu time and begin to stutter. I ended up using a bluetooth audio transmitter [1] (it presents itself as a usb audio device on linux) to work around the issue.

Do you have real time priority configured for the Pipewire (and possibly bluetoothd) process? I had annoying stutter issues before setting that up (Gentoo could not do it automatically at the time, but that may have changed).

I haven't look into it yet. I was trying to get a Bluetooth 5.0 adapter first before trying again, but can't find any at the time. There are plenty of bluetooth 5.0 audio transmitter though, which sidesteps the issue completely.
