This article is somewhat an update of the one named Linux and Bluetooth Headphones. In that article I had tested on (K)Ubuntu 20.04, but this article is about version 22.04.

Just like in the above mentioned article, I recommend that you install and enable PipeWire. It is a lot easier to do in (K)Ubuntu 22.04. The TL;DR version would be:

First, check to see which audio server you're currently on. This command most probably will return 'pulseaudio':

$ pactl info | grep 'Server Name'
Server Name: pulseaudio

So... make sure you install PipeWire:

$ sudo apt update
$ sudo apt install pipewire
$ sudo apt install gstreamer1.0-pipewire libpipewire-0.3-{0,dev,modules} libspa-0.2-{bluetooth,dev,jack,modules} pipewire{,-{audio-client-libraries,pulse,bin,tests}}
$ sudo apt install wireplumber gir1.2-wp-0.4 libwireplumber-0.4-{0,dev}

Disable PulseAudio and enable PipeWire instead:

$ systemctl --user --now disable pulseaudio.{socket,service}
$ systemctl --user mask pulseaudio

$ sudo cp -vRa /usr/share/pipewire /etc/

$ systemctl --user --now enable pipewire{,-pulse}.{socket,service}

Now, you should see PipeWire in here:

$ pactl info | grep 'Server Name'
Server Name: PulseAudio (on PipeWire 0.3.48)

For even more details, read this excellent article.

I tested with EDIFIER NeoBuds Pro and not only that switching between A2DP and HSP/HFP works automagically but, more than that, LDAC codec also works (which previously only worked for SONY WH-1000XM3):
