I have successfully enabled LC3 codec (and thus Bluetooth LE Audio) on my Framework Laptop 16 with Bazzite Linux (Gnome) installed. At least that’s what audio settings and terminal output of bluetoothctl show and bluetoothctl info show me. I have non-factory Intel AX210, but I will retest this with factory-installed AMD RZR616 and update this comment.
All I had to do was uncomment the line in /etc/bluetooth/main.conf
The line is #Experimental = false by default, I changed it to Experimental = true and rebooted the device.
UPD: I forgot to mention that KernelExperimental = was also modified, but despite the instruction I just set it to true.
Your mileage may vary depending on Linux distribution used. I used this guide as example.
If you try to do this on Windows, you should be able to download latest Bluetooth driver AND latest Bluetooth audio codec drivers from Microsoft update catalog or wait and hope for it to happen automatically until the end of this year.
Here is the settings screen:
It works but it is unstable. Not sure what is happening there, but sometimes it works, sometimes it does not, sometimes settings screen don’t even show this drop down item list with codecs and one time all my Bluetooth devices including BLE Mouse disconnected.
Wil be testing this further.
