I have used my Definitive Technology Studio 3D Mini sound bar over Airplay2 with Roon for some time now. It recently quit connecting to my sound bar even though it shows up as an audio endpoint in settings. I am running Roon Server & Remote 2.0 1470 on a Mac Studio Sequoia 15.0.1. I am also running the latest Roon remote on an iPhone iOS 18.0.1. The sound bar works with Airplay 2 from my iPhone using the Apple music application just fine. Any ideas?
