I get the same result: "blueman.bluez.errors.DBusFailedError: br- connection-profile-unavailable" So far none of the remedies offered on the web have helped. What would help is some idea of how the whole BT system works, but the more I look the more complex it seems. Not a direct help, but maybe it will trigger some ideas - the only time I've seen any message about bluetooth profiles has been with a pair of noise-canceling headphones. They work fine for either "High Fidelity PLAYBACK (A2DP Sink)" or "Handsfree Head Unit (HFP)" but the last profile is always "Headset Head Unit (HSP) (unavailable)". These are all in the dropdown for the headset in the pulseaudio voluime control app, once the device is connected. I just connected my BT speaker, and it only shows the first two profiles, so at least it appears to recognizes that it doesn't have a mic. You should be able to get similar info from the bluetoothctl command. Jack

[gentoo-user] Audio stopped working in KVM with libvirtmanager
Audio in KVM (qemu) launched through libvirtmanager used to work fine last time I used it (about 3 months ago.) There has been lots of updates since then, including a switch from Pulseaudio to Pipewire, and something along the way broke it. Now I get no sound whatsoever. qemu doesn't even show up as an application in the audio mixer, nor in the output of "pw-top". If I launch the VM directly through qemu with: qemu-system-x86_64 [...] -audiodev id=audio1,driver=pa then it works fine. But if I launch it through libvirtmanager, it doesn't. Even if I force the use of "-audiodev id=audio1,driver=pa" in the XML of the VM in /etc/libvirt/qemu/, it still doesn't work. There's no error anywhere, no warning, nothing in the logs. Does anyone have any idea what to do?

If the problem still persists, it’s either a system config, a library (cairo, freetype et al, graphics driver) or maybe even a hardware issue. -- Grüße | Greetings | Salut | Qapla’ Please do not share anything from, with or about me on any social network.
