Description of Issue

When I click on a track to play, the track comes up at the bottom, the play icon shows Roon is playing, but no music is audible and the play head is not moving either:

This happens with any track I tried. Yesterday the system was still working fine!

Please help!

Try rebooting both the NAS and the MAC and see if that helps.

Rebooting the core helped.
