No music from my bluesound node

Since a few days I can no longer play my music via Roon core. Roon charges nicely, however when I want to play music (I press play). I see the equalizer of the song but hear no music. Also, the track jumps to the next track after 15 seconds!! Help. I can hear music from my computer (other source), strange!!??
What have I already done? Router restarted, Qobuz logged out and logged in again (connected). Cache memory deleted.
The problem occurs every time I want to start Roon.

The problem is solved! I unplugged the bluesound power supply and plugged it back in. I can enjoy the music again.
