Issues with Airport and Cover Art


I’m just trying out Volumio after I tried HifiBerry OS for some weeks (RPI 3B+ with HifiBerry AMP2 and 3.5" GPIO display and rotary encoder for volume control).
Mostly I use Airplay for streaming which works so far. What is not working with Volumio, but with HifiBerry OS, is the display of cover art or album art via Airplay protocol.
Do I miss something, as this is working out of the box with HifiBerry OS?

Kind regards
