hi @werdem o/

What bluetooth device are you using?

Your version of BlueZ has a security patch for vulnerability CVE-2023-45866 which disables support for certain legacy bluetooth devices.

If your device does not support Classic Bonding, you can re-enable it by setting `ClassicBondedOnly=false` in `/etc/bluetooth/input.conf`, and then running `systemctl restart bluetooth`. More info in https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/2045931/comments/6

Please let me know if that enables your device. Keep in mind that enabling legacy devices enables the exploit.

Hi Mark,thanks for your help, I am not technical expert but I don't think it is because of my headset since it is relatively new device and, the other thing is that I was using this Bluetooth devices(headset, sound bar) without any problem but this problem started couple of weeks ago, so my initial thought was it was because of an OS update,so I created this bug report.From my observation I would say , it might be related to pulseaudio, because the first thing I recognized was that pulseaudio was not starting automatically at the start, then when i started it, it recognizes Bluetooth devices but they are not listed in Settings->Sound->Output, so there is no sound output from the headset.I have tried your suggested solution but no change, also tried some solutions suggested on the web.
