Audio is a problem when pairing Apple TV with a smart TV. We recently “upgraded“ (to get Dolby Atmos) to a Sonos Arc wireless sound system (sub and two Ones for surround sound) to replace our old wired system that was based on a classic receiver/amp, and a new LG TV to replace our aged (sound wise) 2013 LG TV. But the Arc only has one HMDI port and has to plug into the TV’s eArc HDMI port for the system to work. So I have to plug the Apple TV‘s HDMI into another HDMI port on the LG TV. But the LG TV apparently can’t (won’t?) pass through high end audio codec from the Apple TV to the Arc. For example, Netflix on the LG TV plays in Dolby Atmos on the Arc, but Netflix on the Apple TV plays only stereo PCM on the Arc via the TV. I’m not a normally a conspiracy thinker, but … buyer beware. Or maybe I’ve missed something in many hours of scouring the web for setup clues.
