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.
result of the lspci -knn | grep Net -A3; lsusb command :
