Issue/Bug Description: Following the advice here, I've dropped in configuration to add a combine audio output sink (so that my partner and I can watch a movie on an airplane, her with analog output and me with USB output). Since adding this configuration, I have no audio output devices on boot.

Steps to reproduce (if you know):

1. Add combined sink configuration and reboot

   cat <<EOF > ~/.config/pipewire/pipewire.conf.d/add-combined-sink.conf
   context.exec = [
       { path = "pactl" args = "load-module module-combine-sink" }
   ]
   EOF

   ER: a new "combined" output device should appear in sound settings AR: no output devices

2. Restart pipewire and logout and login

   systemctl --user restart pipewire

   ER/AR: "combined" output device beside all other output devices in sound settings

3. Reset combined sink configuration and reboot rm ~/.config/pipewire/pipewire.conf.d/add-combined-sink.conf ER/AR: standard output devices in sound settings

Other Notes: Repro steps above illustrate one workaround while I intend to just create this combined audio sink on demand with the command pactl load-module module-combine-sink. Perhaps this bug report is a hint as to why some other users have similar symptoms?

Wonder if this is similar to my current issue with

pactl load-module module-combine-sink
Failure: No such entity
