Resuming AirPlay Stream to Denon AVR

I’m using AirPlay to stream music to my Denon AVR. When playback is interrupted by the AVR (e.g., switching to a different source momentarily), I cannot get Roon to resume playback. (Roon thinks it is still connected.) Is there some simple way to get Roon to “reboot” its AirPlay stream to the AVR?
