Unable to start pipewire-pulse

Whenever I try and start pipewire-pulse, I get the following in my journal

systemd[2048]: Listening on PipeWire PulseAudio.
systemd[2048]: Started PipeWire PulseAudio.
pipewire-pulse[14782]: mod.protocol-pulse: server 0x556bbeac8670: socket '/run/user/1000//pulse/native' is in use

systemd[2048]: pipewire-pulse.service: Main process exited, code=exited, status=158/n/a
systemd[2048]: pipewire-pulse.service: Failed with result 'exit-code'.
systemd[2048]: pipewire-pulse.service: Scheduled restart job, restart counter is at 1.

It seems to me like systemd is creating the


socket, and then when pipewire-pulse gets launched, it doesn't know how to take over.

This is odd, because the code does correctly handle this: … ver.c#L526

But at the same time, when I remove references to the systemd socket and just start the service:

$ cp /usr/lib/systemd/user/pipewire-pulse.service ~/.config/systemd/user/pipewire-pulse2.service
$ systemctl --user disable --now pipewire-pulse.socket pipewire-pulse.service
$ vim ~/.config/systemd/user/pipewire-pulse2.service # delete all lines referencing pipewire-pulse.socket
$ systemctl --user daemon-reload
$ systemctl --user restart pipewire-pulse2

Everything works fine:

$ systemctl --user status pipewire-pulse2

Any ideas about what's going on here? If this is a bug, I'd expect the impact to be much more widespread.

Re: Unable to start pipewire-pulse

You are starting pipewire pulse or do some pulseaudio client call before the service runs somewhere, potentially before logging in properly.


sudo journalctl -b

remember any autostart services that might have a hand here, e.g. kodi/mpd or so?
