Similar issue here last night.
Mac Mini running core, ultraRendu endpoint.
During streaming, a song would stop and jump to the next track. In at least one case it was repeatable. Largely, the point at which it would stop a track seemed unpredictable.
Fortunately, when we were later listening to the new Leonard Cohen drop (Thanks for the Dance), it played without a hitch. It would’ve been disappointing to have that album interrupted.
I hope we can find a solution for this. It’s annoying, and represents the only major Roon hitch that I’ve encountered.
