I have a pair of Bose QC 45 headphones. I am using Ubuntu 22.04 on my PC. I didn't originally have a Bluetooth adapter, so I bought a UGREEN CM390. It works great out of the box, I tested it with my phone.
The problem is in connecting the headphones to the computer. I can see them through the Bluetooth interface, but when I try to connect them to the computer, it just says they are connected. But in fact, they aren't (no voice confirmation that they are connected).
What I've tried so far:
All the steps in this question: Pair Bose QuietComfort 35 with Ubuntu over Bluetooth
Download the
bluemanprogram and connect through it.Manually remove the device and reconnect it using
bluetoothctl.Use the Bose music app and turn on pairing mode to find the new connection.
Test the Bluetooth dongle w/ headphones on Windows (all works fine)
My guess is that the problem is in the drivers or in the protocol itself (the UGREEN CM390 uses Bluetooth version 5.3).
If you have any suggestions, I would greatly appreciate it! Thank you!
