Hi all, I'm using pipewire, version above. I have installed it following the suggestions reported in gentoo documentation , systemd option. Sound works just fine, no issues so far. However, whenever I log in into kde (sddm) I have to run systemctl --user restart pipewire.socket pipewire-pulse.socket otherwise no application will be able to connect. If I enquiry the status of the units via systemd, they are reported to be working and pipewire/pipewire-pulse are present as processes. I have no real idea how to proceed further to debug or provide more details. Reproducible: Always

Let's try some basic checks. Please provide the output of these commands while the issue is present: ps aux | grep -E pulse\|wire echo $XDG_RUNTIME_DIR ls -l /run/user/*/{pipewire,pulse/}* pw-cli --version wpctl status pactl info systemctl status | head systemctl --user status | head ls -l {/etc,$HOME/.config}/{pipewire,wireplumber} Hopefully one of these will give some insight on where to look further.

I'm not sure if that's the entire reason but your $XDG_RUNTIME_DIR is set to a surprising value - it's usually /run/user/<UID> rather than /var/tmp/<username>. Also I observe that /var/tmp is usually persistent tmp but XDG_RUNTIME_DIR, I believe, should be always tmpfs backed but that's mainly a correctness issue. After you restart the daemons the sockets end up being moved from the usual/correct /run/user/1000/ to the /var/tmp/cova and then it starts working but I'd still suggest not overriding XDG_RUNTIME_DIR to /var/tmp/cova in the first place. Thank you for also providing the output after the issue is cleared by the daemon restart - I was going to ask for that now but it's already available. ;) I think there's a bit of a surprising behavior in that PipeWire somehow picks up the new XDG_RUNTIME_DIR but the systemd socket files still create the old placeholders inside /run/users/1000 - I'm not sure why that works rather than becoming fully broken. I'll try bringing up with the upstream to see if such behavior is expected and desired (arguably your system is broken but that doesn't change that the observed behavior is unusual enough that it would be best to understand why and how it ends up working anyway). I'm also a bit unsure why there's = and the end of socket files for both PipeWire (/run/user/1000/pipewire-0=) and PulseAudio (/run/user/1000/pulse/native=) but I can't immediately come up with an explanation for that. Perhaps you have an idea? If the socket filenames really end with = that could also cause the issue, since I don't think any software is anticipating that. What does this return after the daemons have been restarted: ls -l /var/tmp/cova/{pipewire,pulse/}*
Sorry, I meant /run/users/<UID> not the singular user I wrote in my reply.
Also I forgot that you should check with `systemctl list-units --failed` to figure out which systemd unit failed and try to fix that since in rare occasions that can lead to surprising system behavior if the unit that failed happens to be important to the boot process (though in this case it's probably all related to the XDG_RUNTIME_DIR override).

Nailed it! For some reasons (I guess a since long forgotten debug session for some other weirdness common with Gentoo ~ :) ) I had that setting laying around. I removed it an now pipewire starts without issues. Great catch. > I'm also a bit unsure why there's = and the end of socket files for both > PipeWire (/run/user/1000/pipewire-0=) and PulseAudio > (/run/user/1000/pulse/native=) but I can't immediately come up with an > explanation for that.

This is only a "ls" artifact. launching it with ls -la --indicator-style=none --color=never /run/user/1000 creates a clean list: ⌙➤ ls -la --indicator-style=none --color=never /run/user/1000 total 4 drwx------ 9 cova cova 400 May 13 08:59 . drwxr-xr-x 3 root root 60 May 13 08:57 .. srwxr-xr-x 1 cova cova 0 May 13 08:57 Alacritty-:0-3746.sock srwxr-xr-x 1 cova cova 0 May 13 08:59 Alacritty-:0-4154.sock -rw-r--r-- 1 cova cova 71 May 13 08:57 KSMserver__0 drwx------ 2 cova cova 60 May 13 08:57 at-spi srw-rw-rw- 1 cova cova 0 May 13 08:57 bus drwx------ 3 cova cova 60 May 13 08:57 dbus-1 drwx------ 2 cova cova 60 May 13 08:57 dconf prw------- 1 cova cova 0 May 13 08:57 fish_universal_variables.notifier dr-x------ 2 cova cova 0 May 13 08:57 gvfs drwx------ 2 cova cova 40 May 13 08:57 gvfsd srw------- 1 cova cova 0 May 13 08:57 kdeinit5__0 srwxr-xr-x 1 cova cova 0 May 13 08:57 klauncherBJMxdW.1.slave-socket srwx------ 1 cova cova 0 May 13 08:57 org.keepassxc.KeePassXC.BrowserServer srw-rw-rw- 1 cova cova 0 May 13 08:57 pipewire-0 -rw-r----- 1 cova cova 0 May 13 08:57 pipewire-0.lock drwx------ 2 cova cova 80 May 13 08:57 pulse drwxr-xr-x 6 cova cova 160 May 13 08:57 systemd So now pipewire works just fine, thanks for the hint!!!
