Description of Issue
I can’t play music to the Apple TV through the Roon Zone for the Apple TV.
I’m using the Roon app installed on the Core.
This is OK: In the Roon app, when I use the SystemOutput zone in Roon, I can play music to the Apple TV, when the Mac mini system output is set to the Apple TV (System Preferences → Sound → Output tab → select the Apple TV).
This is the PROBLEM: In the Roon app, in Settings → Audio, the Apple TV shows up as Roon Tested. It is enabled. (The Mac mini system output set to “Mac mini speakers”.) When I select the Apple TV zone in Roon and click the Play control in Roon, the status “dot” to the left of the Previous control lights green (sometimes amber) for a second or two then returns to gray. The Play control changes from displaying Pause to displaying Play.
Also OK: My iPhone also has no problem playing my Apple Music to the Apple TV.
