After I updated Ubuntu from 20.04 to 22.04, my system cannot connect to my Huawei Freebuds 3 bluetooth headphones anymore. When I click on the headphones in the devices list, it tries to connect for a while, until it stops. I already removed the device and tried to pair again, but with the same result.

I tried to establish an connection on the command-line via bluetoothctl as described in this blog article, but the result is the same, and it doesn't report any error. Is there a command-line tool for bluetooth that actually outputs a useful log/error message?

Furthermore, I tried this suggestion, but after re-installing pulseaudio-module-bluetooth, sudo pactl https://askubuntu.com/a/1369477/515475 reports the error

Connection error: Connection refused
pa_context_new() failed: Connection refused

pactl list modules shows:

Module #10
    Name: module-bluetooth-discover
    Argument: 
    Usage count: k. A.
    Properties:
        module.author = "João Paulo Rechi Vita"
        module.description = "Detect available Bluetooth daemon and load the corresponding discovery module"
        module.version = "15.99.1"

Module #11
    Name: module-bluez5-discover
    Argument: 
    Usage count: k. A.
    Properties:
        module.author = "João Paulo Rechi Vita"
        module.description = "Detect available BlueZ 5 Bluetooth audio devices and load BlueZ 5 Bluetooth audio drivers"
        module.version = "15.99.1"

I just managed to solve it. This answer was almost the solution to my problem. After re-installing the module, I should first unload the module, before loading it again. Furthermore, I shouldn't have used sudo, this doesn't need root permission.

sudo apt install --reinstall pulseaudio-module-bluetooth
pactl unload-module module-bluetooth-discover
pactl load-module module-bluetooth-discover

Installing package "blueman" will help you.

First launch the terminal by pressing ctrl + alt + T

Then run the command in terminal:

sudo service bluetooth start

Install blueman by typing to terminal:

sudo apt install bluetooth blueman bluez-tools bluez-hcidump bluez

Now again type to terminal:

sudo service bluetooth restart

If not installed, install blueman:

sudo apt install blueman

Now launch Blueman and then connect your devices from the blueman window by searching followed by pairing.

The previous answer doesn't work for me. My headphone is Beats Studio 3. I installed blueman, but it still fails to pair.

I finally solved the problem by changing the visibility setting provided by blueman to always visible.

One of the solutions is to press the Play/Pause button after you pair the system and the device. This will make the gnome sound manager have the A2DP available. With this option on you can easily set the audio output in the menu. Although this solution isn’t ideal, it does the job.

Forget the device from your Bluetooth list. Then run the command:

sudo systemctl restart bluetooth

Re-pair your headphones.

This worked for me.

Working with a Kinesis Advantage 360 Pro keyboard, I found out that the bluetooth profile did not clean itself up after a manual disconnect. I had to "clear" the bluetooth profile from the device. It immediately attempted a re-connection and worked.
