Since I updated to Ubuntu 22.04, bluetooth has been broken and I cannot seem to connect my bose quietconfort 2 to my laptop, I've tried every answers I found on the Internet, but since nothing is working Im asking here. My headphones are most of the time plainly refusing to connect, and the rare times I manage to connect them, they just disconnect or play garbled sounds.
Here a the thing I tried : messing with the /etc/bluetooth/main.conf file and putting bluetooth to bredr, pairing through the bluetoothctl command, I tried unpairing and pairing them again, using blueman.
My laptop is a lenovo ideapad 5 pro.

I was having trouble with Bose Soundlink2, the following worked for me. I was using Ubuntu 20.? and then migrated to 22.04. The same thing fixed the newer OS version. Also I had issues with volume but in 22.04 it seems to have been fixed for me.
Install:
sudo apt-get install blueman
sudo /etc/init.d/bluetooth start
bluez-tools :
sudo apt-get update -y
sudo apt-get install -y bluez-tools
bt-device -r <mac adress bluetooth speaker>
