In order for Wireplumber to be used by Pipewire, Wireplumber must be 
configured to start when a desktop environment is started.

To configure Wireplumber to start when a desktop environment is started
, run the following commands as the root user to enable the systemd 
user units:


systemctl enable --global pipewire.socket 
systemctl enable --global wireplumber 

Enable the wireplumber service and the pipewire-pulse socket; enabling 
the pipewire-pulse socket will cause the pipewire-pulse service to be 
started if required. That service will in turn start the pipewire 
service.

systemctl --user enable --now pipewire-pulse.socket wireplumber.service
systemctl --user enable --now pipewire.service
