Fix headphone bluetooth keep disconnecting Ubuntu

After applying Pipewire with AAC support in Ubuntu 24.04, I got problem where my Bose QuiteComfort is repeatingly disconnecting. The log keep saying input failed to connect

grep blue /var/log/syslog

I did several things like re-install packages and configure the bluetooth /etc/bluetooth/main.conf with AutoEnable=true and ControllerMode = bredr still not working. Also edit /etc/bluetooth/input.conf with `UserspaceHID=true`.

Turns out this solution at https://knowledgebase.frame.work/ubuntu-bluetooth-S1PGxfho works well!

sudo rm -r /var/lib/bluetooth/
rm ~/.config/pulse/* 
sudo apt reinstall --purge bluez gnome-bluetooth
systemctl restart bluetooth

This will remove your headphones from bluetooth (*reset). Then change your headphones mode into pairing mode.

Then do this to enter the bluetooth terminal

bluetoothctl

Then lets find and pair

power on
scan on
pair Device ID
devices
trust ID

If any notification asking for authorization, then choose “yes”. This is usually causing the problem where paired bluetooth is not authorized. next time its connected, its get problem!
