Bug Description

Recently upgraded to 22.10 (from I believe 20.04, not actually completely sure) and both of my Bluetooth devices have stopped working.

They can pair and connect initially, but disconnect after 4-5 seconds.

My headphones worked a while, but have not since been able to have them stay connected.

Here's an output from bluetoothctl, which doesn't say much?

I'll try it when I have a free usb stick available here. Although I'm on
22.10 currently, but I guess that's not entirely relevant
