Hi @Martin_Simon,
Can you please provide some more information regarding your setup here by using this thread as a guide?
Have you tried logging out and back into Qobuz? You can do this in Roon Settings -> Services Tab.
Are you able to play tracks all the way until the end when using the Qobuz web player (play.qobuz.com)? Please try playing a track until the very end and not just the first few seconds.
Thanks,
Noris
