Using LG Oled and AppleTV - I replaced Sonos Beam with two Play 5 gen 2 white speakers and Sub as room 2. I added Sonos Port as Room 1. Using HDMI 2 ARC , the Oled Audio is fed to an HDMI to analog converter that uses rca to send the LG sound to the Port line in. Set up was easy and I use Port as room1 then add stereo paired room 2. Music apps sound amazing ! Controlling volume and mute with Apple TV remote works perfectly. Opening the Sonos App and adding rooms / changing volume etc works the same as with the Beam. Using the App I can visually see and hear the volume changes as I make them. When using the Apple TV remote to change volume … change is heard but the Sonos App volume sliders remain in place.
Sonos Port line in volume changes are not displayed in Sonos App.
Also I first tried a Sonos Connect but it is not supported in the current Sonos App.
