[SOLVED] [runit] Pipewire crashes after suspend

Hey guys,

I've encountered another problem for which I couldn't find a solution yet. So I am using XFCE without a DisplayManager, i.e. I am logging in through tty1 and autostart startx via .bash_profile. So for Pipewire to work, I start it on startup through .xinitrc:
Code: [Select]
pipewire &
pipewire-pulse &
pipewire-alsa &
wireplumber &
xrdb ~/.Xresources
exec startxfce4

Everything works fine until I close my laptop lid which causes my machine to suspend. Afterwards, when I want to continue to work, everything works except audio. Pipewire does not work anymore and starting it manually gives me some error messages:

Code: [Select]
$ pipewire
[E][00460.402869] mod.protocol-native | [module-protocol-:  610 lock_socket()] server 0x560a356e9d70: unable to lock lockfile '/run/user/1000/pipewire-0.lock': Die Ressource ist zur Zeit nicht verfügbar (maybe another daemon is running)
[E][00460.403116] pw.conf      | [          conf.c:  412 load_module()] 0x560a356ac5f0: could not load mandatory module "libpipewire-module-protocol-native": Die Ressource ist zur Zeit nicht verfügbar
[E][00460.403362] default      | [      pipewire.c:  123 main()] failed to create context: Die Ressource ist zur Zeit nicht verfügbar

So as it seems, Pipewire is still running but not properly anymore. I have searched the Arch wiki entry and the Internet for a clue on how to maybe automatically restart the service but so far I could not find anything useful, or if this would even be the proper solution. So now I have to ask you, guys, what can one do in this situation?

Edit: The solution to this problem is to disable bluetoothd because as of version bluez-5.63-1 it interferes with wireplumber (and pipewire-media-session) causing wireplumber to crash when waking up from suspend.

If it is your .xinitrc you need first to rtfw.
Also you need to run your DE in a dbus session so you need to actually exec dbus-launch

Found via https://searx.fmac.xyz/search?q=runit+service+after+suspend

So basically I have to symlink pipewire and wireplumber to /usr/lib/elogind/system-sleep such that elogind can handle to execute them again after suspend?

Sorry, I could not understand the first sentence since I do not know the abbreviation "rtfw".
Regarding your second point: I have activated the dbus-runit service. So I still need to add "exec dbus-launch" to my .xinitrc? And if I am right, I have to add it before "exec startxfce4"?

Remember that lines following a command using exec would be ignored.

This is because
Code: [Select]
$ man bash
then type literally /^ +exec (space at the end, then Enter):
Quote
       exec [-cl] [-a name] [command [arguments]]
              If command is specified, it replaces the shell.  No new process is created.  The arguments become the arguments to command.  If the -l option is supplied, the shell  places
              a  dash  at the beginning of the zeroth argument passed to command.  This is what login(1) does.  The -c option causes command to be executed with an empty environment.  If
              -a is supplied, the shell passes name as the zeroth argument to the executed command.  If command cannot be executed for some reason, a non-interactive shell exits,  unless
              the  execfail  shell  option is enabled.  In that case, it returns failure.  An interactive shell returns failure if the file cannot be executed.  A subshell exits uncondi‐
              tionally if exec fails.  If command is not specified, any redirections take effect in the current shell, and the return status is 0.  If there is a redirection  error,  the
              return status is 1.

What to do if I have a problem:

First go through wiki.archlinux.org and wiki.artixlinux.org and use the relevant parts (all except the systemd commands on the archlinux wiki) to set up your system really correctly.

Look at the internet to see if anyone has had a similar error (at least 90% of problems have already been solved on the internet before you) - often a question of 5 minutes before solving it here for days and peoples here will look at the internet anyway :-)

Thanks for your hints and help. I read through the wiki entries and adjusted my .xinitrc accordingly:

Code: [Select]
$ cat .xinitrc 
pipewire &
pipewire-pulse &
pipewire-alsa &
wireplumber &
xrdb ~/.Xresources
exec dbus-launch startxfce4

I read through man 1 loginctl, especially the "Hook directories" part and as far as I understand it, I have to place executables of pipewire and its components to /usr/lib/elogind/system-sleep in order for elogind to manage these programs when suspending my system. Am I right?

Quote
   Hook directories
       [/usr]/lib[64]/elogind/system-sleep/, /etc/elogind/system-sleep/
           Immediately before entering system suspend and/or hibernation elogind will run all executables in
           [/usr]/lib[64]/elogind/system-sleep/ and /etc/elogind/system-sleep/ and pass two arguments to them. The first argument will be
           "pre", the second either "suspend", "hibernate", "hybrid-sleep", or "suspend-then-hibernate", depending on the chosen action.
           Immediately after leaving system suspend and/or hibernation the same executables are run, but the first argument is now "post".
           All executables in this directory are executed sequentially, and execution of the action is not continued until all executables
           have finished.

Not directly pipewire executable, as it doesn't parse the arguments sent by elogind. Rather, something like the script given as an example here:
https://wiki.archlinux.org/title/Power_management#Hooks_in_/usr/lib/systemd/system-sleep

Thanks for the hints
Now I understand what elogind actually does in this case and why it is handy to use a shell script to parse the arguments and use them in order to tell the system what to do before (pre) and after (post) suspend etc.
As the noob I am, I'm tempted to killall pipewire and wireplumber processes post suspend and restart them again. But this doesn't seem to be an elegant solution at all. There would also be the problem of waiting for the processes to shutdown properly before starting them again. Would there be a more gentle way to solve this?

Why not? That's how daemons and processes in general are managed, unless they include a different method. Pipewire doesn't.

Code: [Select]
man kill
Quote
       If no signal is specified, the TERM signal is sent. The default action for this signal is to terminate the process. This signal should be used in preference to the KILL signal
       (number 9), since a process may install a handler for the TERM signal in order to perform clean-up steps before terminating in an orderly fashion. If a process does not terminate
       after a TERM signal has been sent, then the KILL signal may be used; be aware that the latter signal cannot be caught, and so does not give the target process the opportunity to
       perform any clean-up before terminating.

Code: [Select]
man 7 signal
man wait
man pidof

All right, thanks for the hints!

This is what my sleep script now looks like:
Code: [Select]
$ cat /usr/lib/elogind/system-sleep/00-pipewire.sh 
#!/bin/sh

pid_pipewire=$(pidof pipewire)
pid_pipe_pulse=$(pidof pipewire-pulse)
pid_wireplumber=$(pidof wireplumber)

case $1/$2 in
  pre/*)
    ;;
  post/*)
    kill $pid_wireplumber
    wait $pid_wireplumber
    kill $pid_pipe_pulse
    wait $pid_pipe_pulse
    kill $pid_pipewire
    wait $pid_pipewire

    pipewire &
    pipewire-pulse &
    wireplumber &
    ;;
esac

Any objections to that? :)

wait is unnecessary here, as all those programs are well behaved. It is enough to just issue kill command, and, since it accepts multiple arguments, just one kill command is enough:
Code: [Select]
kill $(pidof pipewire) $(pidof pipewire-pulse) $(pidof wireplumber)
Of course, you could refine (or complicate) this further by checking if the processes terminated and giving a timeout, after which SIGKILL is sent, but in my opinion it is unnecessary.

Thanks again for your input, @strajder !

I've adjusted my script according to your explanation, restarted the system and tried it out by closing and opening my laptop lid. Unfortunately, it still does not work. But now it seems that the pipewire processes get killed as intended but the part of the script where they should be started again does not. I can now manually start them without any errors, though.

Maybe this is because the script tells them to start pipewire etc again even though the old processes might not be shutdown correctly yet?

The problem still persists, unfortunately. This is how my script looks like right now:

Code: [Select]
$ cat /usr/lib/elogind/system-sleep/00-pipewire.sh
#!/bin/sh
case $1/$2 in
  pre/*)
    kill $(pidof pipewire) $(pidof pipewire-pulse) $(pidof wireplumber)
    ;;
  post/*)
    pipewire &
    pipewire-pulse &
    wireplumber &
    ;;
esac
