Bluetooth error on Arch-based system with Plasma

Hello, I’m having trouble with my audio devices when connecting with bluetooth; they connect but there’s no sound, then after a few seconds it disconnects. This happens on EOS as well: I’m new to this OS and Linux as a whole so I don’t know how I can troubleshoot, but I can follow instructions.

Thank you in advance

Try connecting it manually through terminal with bluetoothctl.

Hi, I’ve tried this and it worked at first, but after reboot it’s broken again.

Here is the error in the journalctl log: This happens every connection:

Another thing is that the earbuds worked before on EOS but then stopped working, and it persisted to Cachy. However I’ve just bought a headphone and its bluetooth is also currently working fine. I dont know what to make of this trend.

I would try earbuds on another device, phone. Also use trust command in bluetoothctl for future convenience.

Ok, headphones have been working splendidly for the past few days between both OSes. So I think it might be a hardware issue. Searches suggest it is a driver issue, but I’m not sure how to find out the specific problem: at the very least it is related to how the earbuds connect. (Defunc True Basic)
I don’t know the technical details but are there different methods of bluetooth connection?
