Hi Jan,
seems like your system doesn't have any Phonon backend installed (any
more). I believe you'll need to install the package
"phonon4qt5-backend-vlc".
(Amarok is one of the few applications using Phonon for audio playback,
so it is not unexpected that you are not experiencing issues with other
software's audio)
Best regards
Tuomas

Hello,
I loved Amarok 1 and Amarok 2, so I was very happy about the release
of Amarok 3, and I installed it on my Linux PC (Tuxedo OS) some month
ago. It worked a couple of months without any problems, but since some
weeks it doesn't work anymore.
Amarok starts and shows my music collection, but when I press "Play",
Amarok doesn't play the music, and the progress bar doesn't show any
progress. When I start amarok from a terminal, I get the following
messages:

I'm wondering about all the "phonon"-messages. Other media players -
e. g. "mpv" - use "pipewire" as audio output.
