Bluetooth qui ne fonctionnne plus depuis passage à Debian 12

Bonjour depuis mon passage à Debian 12 (réinstallation complète) le bluetooth ne fonctionne plus. Voici ce que j’obtiens :

Je dirait au hasard :

a2dp-sink profile connect failed [...]: Protocol not available
This error can appear when using PipeWire as your audio server and attempting to pair a device via Bluetooth, without first uninstalling the pulseaudio-module-bluetooth package.

If you're using PulseAudio, PulseAudio may not be properly connecting to the device. It might be because it was already playing. Stopping anything playing on PulseAudio, restarting PulseAudio, and reconnecting to the device may fix the problem.

In addition, you need the following settings in /etc/pulse/default.pa or /etc/pulse/default.pa.d/bluez5.pa:


load-module module-bluez5-device
load-module module-bluez5-discover
Then restart pulseaudio.

sudo apt-get install bluetooth blueman bluez bluez-obexd bluez-firmware pulseaudio-module-bluetooth gnome-bluetooth-3-common gnome-bluetooth-sendto ubertooth

et
sudo modprobe btusb ; sudo systemctl enable bluetooth.service ; sudo systemctl start bluetooth.service

Eventuellement sudo systemctl -f start bluetooth.service

J’ai eu le même ennui, ça correspond au changement de manière de gérer Bluetooth entre les versions 11 et 12, qui passe de pulse-audio à pipewire-audio et qui n’est pas bien mis à jour lorsqu’on upgrade visiblement.
En suivant la discussion ici, j’ai réinstallé pipewire-audio.
Je cite, « Celui-ci va désinstaller les paquets pulse-audio et installer les paquets qui vont bien. »
Et effectivement, ça a bien marché pour moi…
