I have to restart wireplumber in order to work

Support Sound
1

Hello!

I have two installations, KDE and Gnome. Both need systemctl --user restart wireplumber on start, after lock, after suspend, in order to work. Without it my apps are connecting to a “dummy” output (no sound with no errors).

wpctl status

Normal output after restarting:

Hi @adrian,

Is the service enabled? Check with:

systemctl --user status wireplumber

if not enable it:

systemctl --user enable wireplumber

…and test.

Hope this helps!

It is enabled (with some warnings)

systemctl --user status wireplumber
