No sound via Airplay

Can’t get Roon to play via Apple TV thru my home theater system. Latest ATV/Latest IOS/Nucleus.
Can choose the Zone, it shows it’s playing music on the Roon Controller on iphone but I hear nothing. I disabled and reenabled with the password shown on ATV and still nothing. Spotify/Tidal/and iTunes Music that is downloaded on my phone all play fine. What gives? Any help appreciated. Thanks!
