I have Sonos ARC, Sonos SUB and 2 IKEA Symfonisk as Rear.
(Looking at Netflix in AppleTV connected to Samsung Q95 tv, connected to Sonos ARC with HDMI-eARC)
The app says i got Dolby Atmos (like the picture). One guy says that i need to have 2 Sonos ERA300 as rear to get Atmos. And the app is just fool me.
is it so? What is right?
