I had pulseaudio installed when upgrading to daedalus and the devices did not 
appear in first place with pulseaudio. I installed pipewire just to try to 
solve. I installed pipewire acording to:
    https://dev1galaxy.org/viewtopic.php?id=5867
...and yes I installed pipewire-audio pipewire-pulse pipewire-alsa and 
pavucontrol-qt*.

This is done in .xsessionrc.

The problem does not seem to be related to the sound system, there are a few 
posts, that describe the same problem, like for example:
https://discuss.kde.org/t/kde-disappeared-audio-devices/5579/1
    or
https://discussion.fedoraproject.org/t/audio-device-not-visible-or-usable-in-kde-settings-until-a-profile-is-assigned/74851
...it seems related to some KDE oddities.

I do not have access to the machine, its from someone else some 30KM away. So
I cannot try your suggestions at the time. I was hoping that someone had the
same problem when upgrading and remembered what the problem was.

I'll try your suggestion with backports, when get my hands on that machine.
Thanx!
