I have a Sony WH-CH700N Bluetooth Headset. On my previous Ubuntu it worked perfectly fine. Now I'm using a different notebook with Kubuntu on in and I can't use it.
It's detected immediately. Strangely I am not able to select an Audio Profile. Also, I can't do anything meaningful in "Setup" (it just says it's configured successfully).
It also can obtain the information from the device: 
The headset usually gives an audio Feedback saying "Bluetooth Connected", but that's not happening.
I started to go through the tutorial on how to use pipwire ()
I have installed pipewire successfully. In some tutorials it was required to restart pulse and nothing happened. Restarting pipewire interrupts the playing sound and give a visual feedback. Also:

When I try to connect the headset it looks a little wrong:

What I don't understand is that several guides advice the installation of ofono, while pipewire seems to not like ofono.
I am aware this is (unfortunately) quite common issue under Linux. But I did some further research and wonder what happened to bluez-firmware in 20.04?
$ sudo apt-get install bluez-firmware Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package bluez-firmware Edit(1): The reason why I want to install it is because I assume there's something going wrong with my bluetooth:
lsusb | grep Bluetooth doesn't return anything.
On the other hand the service is running:

So I went to and downloaded the iwlwifi-9000-pu-b0-jf-b0-34.618819.0.tgz and moved the files to /lib/firmware.
Also no blocking:
$ sudo rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no I have also tried already to turn off the wifi and connect. No difference.
After trying a lot at some point I was not even able to pair it any more. But thanks to () I could do it again. Yet, there is still no audio connection.
On pairing in the command line with bluetoothctl I get this information:

Edit (4): I have tried it with bluetooth dongles instead of the internal bluetooth. No success either. This makes me believe it's a software-related error. I have installed the newest bluez-version from the sources. I'm not able to compile blueman, so I used the one from apt.
Reset to default
