I have the latest Apple TV 4K (2nd generation) and a new 2021 65” Samsung Q70A tv and a Sonos ARC paired with two Sonos one SL’s. When using the native apps on the Samsung TV everything work great. I get Dolby Atmos sound with the apps that support is and the sound is fantastic. When I use the Apple TV 4K, I consistently have issues with the audio dropping. We use the DirecTV Stream app the most, and the problem occurs there a lot. This was also the case when it was AT&T TV. When starting the app, sometimes there is no audio and if we keep changing channels, it eventually will work, but then stop again sporadically. Also sometime the sound works fine at startup, but will drop when changing channels. All devices are up to date with firmware and I have tried every combination of settings and recommendations from Sonos, Samsung and Apple forums. Does anyone have this same setup (or similar) and have a solution?
