I have read the ArchWiki's Bluetooth page for the help, and I can confirm that the problem was caused by dual-booting and connecting my bluetooth headset to both of them. If the outputs are needed, please reply and I'll post them out.

I've followed the dual-boot instructions in the ArchWiki, but the problem turns into Connection refused (111) after I changed the key, rebooted and wants to connect to the headset. This is the journal output:

So apparently I need to remove the device and reconnect it again to make it work and not disconnecting like every 5 seconds. But now I only get those low-quality audio profiles.

#4

And apparently there is something to do with pipewire, but I need to turn these into pipewire commands. Does anyone knows that?

#5

I was just trippin' away one day while dual-booting Arch and Windows when I noticed I no longer had Bluetooth capability. In either OS. Something had switched it off. Some hardware detector thingee, I guess.

In order to fix the issue permanently, I had to go into my BIOS and change the Fastboot option from Minimal to Thorough. That let the BT hardware be re-acquired in Linux & Windows.

I'm not the only person to have this happen. I'm also not the only person that needed to use this 'fix.'
