Problem

After startup of my desktop I cannot use any audio interface. I’m using KDE Plasma and the volume control shows “Connection to the sound service lost”. This problem did not exist for me in the Fedora 40 installation.

Cause

Not yet known.

Welcome to Fedora @swillage

systemctl --user status wireplumber pipewire pipewire-pulse
Can you see some errors while showing the status?

Good idea, thanks.
This is the output of the command:

after I restart the audio with my command above all three servicec switch to Active.

Best

/sw

Ok, as you can see the status of pipewire & pipewire-pulse is presenting the preset status as disabled.

Try to activate the the two inactive services with the command as described here:

foo is the placeholder for the service names you want to activate. You can substitute it with the two service names

Enable a service to be started on boot:

# systemctl enable foo

Thank you. I enabled all three services, now after startup status shows this one:

The audio still does not work after startup. After my restart command above it works again. Status now is more or less unchanged.
