As a non-gnome (and non-display-manager) user, I share these .xsession
snippets:
# Required by pipewire, at least
export XDG_RUNTIME_DIR=$(mktemp -d/tmp/$(id -u)-runtime-dir.XXX)
# Required by most things
eval `dbus-launch --sh-syntax --exit-with-session`
pipewire &
pipewire-pulse &
(sleep 2 ; wireplumber & ) &
There wasn't a pipewire-specific config; it uses the same ALSA backend
as pulseaudio used.
If you don't mind answering, was it a Rhode Island Red cockerel or a hen
which you sacrificed to learn these arcane secrets? And, full-moon at
midnight, or dark of the moon? Or did this take moving up to a goat?
Or are you a graduate of Hogwarts? Because I am quite sure that none of
these snippets show up anywhere in the so-called documentation. Pure
magic, just like any sufficiently advanced technology.
That's because they aren't necessary. For any standard desktop all
those pieces are already setup for you. Notice how he said
"non-display-manager user". Those are only necessary if you don't have
a graphical login session.
Non-display-manager user or not, those might be necessary even if you
have a graphical login session. I installed the KDE spin of Fedora 35 on
Monday. A bare metal install: I partitioned the sda drive and formatted
it during the install.
I had NO audio. And nothing I did allowed the system to even *find* any
audio hardware. I played a fugue's worth of combinations and read
everything I could find.
Unfortunately, as noted in this thread, there is no install guide. It
just works - NOT. I saw an error message about XDG_RUNTIME_DIR and spent
most of an evening down that rabbit-hole, but nothing worked. Pipewire
would not even find a module which its own rpm had installed. In the
end, I basically inverted the lines of the install process script I was
playing with, and re-installed pulseaudio.
Audio works fine now. My opinion of pipewire is, that like pulseaudio
and systemd were, it has been released far too early in its beta stages.
It took a couple of years for each of pulseaudio and systemd to reach
adequate levels of instalability and reliability. Likely the same for
pipewire.
