I have a Muso and a a Muso QB as part of my set up . Everything works fine through Airplay however when I first started using Roon the physical controls on the device ( play, pause etc) still worked . The volume on the Muso still works but not any of the other physical controls and I don’t know what has changed . I can still control the Muso’s from the Roon app but sometimes pressing pause on the top of the device is so much easier - any ideas ?
