After upgrade to F40 my device Galaxy Buds 2 Pro audio doesnt works anymore.
In a Boxes Virtual Machine i put an clean Fedora 39 and then works.
In a boxes Virtual Machine in a clean Fedora 40 install doesnt works too.
Bluez tells that the device is recognized as “unknown”.
The device appears on Bluetooth section to pair, but is not recognized as an bluetooth audio device and doesn create an audio output like on fedora 39.
Works fine here. Could be related to your bluetooth chip? Also check for a firmware update for the buds.
Try reinstalling the bluetooth stack (this will wipe all your devices!):
rm -rf /etc/bluetooth
rm -rf /var/lib/bluetooth
sudo dnf reinstall "bluez*"
reboot afterwards
@principis thanks for the tip.
After a few configs i tried:
rm -rf /etc/bluetooth
rm -rf /var/lib/bluetooth
sudo dnf reinstall "bluez*"
But this changes doesnt works.
I had to do something else:
sudo dnf swap wireplumber pipewire-media-session
After swipped back to pipewire-media-session and reboot, the buds device worked for me
