I was about to comment on Bug#998220, but I changed my mind. I do have `pipewire` installed. For one thing `libpipewire` is in the dependencies of `kwin- wayland`, so it's a requirement on my system.
After last upgrade (sid) a couple of days ago, bluetooth headset were refusing to connect, "Protocol not available". But they were willing to connect if I was before doing: (after each reboot) `systemctl --user restart pulseaudio.service` Then I decided to do some searches, and here is what came from it. I'm putting it here because it's not sure at all that every bit of what I did was really necessary. Specifically, were the libraries `libspa-0.2-bluetooth` and `pipewire-audio- client-libraries` really needed. Or even just `libspa-0.2-bluetooth`. === I do initially, have the following issue: `otherwise device connections will fail with "Protocol not available".` (https:// wiki.debian.org/PipeWire) Here is an edited version of how I fixed it on #debian-next: === Giving the ubuntu tuto a try now (https://askubuntu.com/questions/1339765/replacing-pulseaudio-with-pipewire-in-ubuntu-20-04) `sudo aptitude install libspa-0.2-bluetooth pipewire-audio-client-libraries` `systemctl --user daemon-reload` (as plain user, other terminal) `systemctl --user --now disable pulseaudio.service pulseaudio.socket` `systemctl --user mask pulseaudio` => `Created symlink /home/chris/.config/systemd/user/pulseaudio.service → /dev/null.` `systemctl --user --now enable pipewire-media-session.service` => `Failed to enable unit: Unit file /etc/xdg/systemd/user/pipewire-media-session.service is masked.` Here I'm suggested to use the two pivotal following lines: `sudo aptitude purge pipewire-media-session` `sudo aptitude reinstall wireplumber` => "Created symlink /etc/systemd/user/pipewire-session-manager.service → /usr/lib/ systemd/user/wireplumber.service." I still have "device connections will fail with "Protocol not available"." `systemctl --user restart pipewire` There it is. Bottom line: I did not follow https://wiki.debian.org/PipeWire which contains things not possible to do. I followed https://askubuntu.com/questions/1339765/replacing-pulseaudio-with-pipewire-in-ubuntu-20-04 With `pipewire-media-session` replaced by `wireplumber`. I did do `apt purge --autoremove pipewire-media-session` and then `apt install --reinstall wireplumber` And `systemctl --user restart pipewire` I didn't do: `touch /etc/pipewire/media-session.d/with-pulseaudio`, nor did I do: `cp /usr/ share/doc/pipewire/examples/systemd/user/pipewire-pulse.* /etc/systemd/user/` (from https://wiki.debian.org/PipeWire) The line: "Install pipewire-pulse (which replaces pulseaudio and pulseaudio-bluetooth)" from https://wiki.archlinux.org/title/bluetooth_headset suggests that the two latter packages should be removed (not sure about that, just saying) I rebooted to see if it'd be still working: it auto connected very very quickly. And audio is working. === Packages: https://packages.debian.org/sid/libspa-0.2-bluetooth[1] and https:// packages.debian.org/sid/pipewire-audio-client-libraries[2] are saying that they are "experimental". That could explain why they are not in the dependencies. But they seem to work.
