Hello,I have a TV model LG-55LA620V, Google TV Streamer and Sonos Arc Soundbar with 2x Sonos Play:1(surround) added. The problem is that I can't get Dolby Atmos sound to work, only dolby digital 5.1. The cables are HDMI 2.1 and connected as follows: - Google TV streamer -> Tv HDMI 3 (MHL) - TV HDMI 1 (ARC) - Sonos Arc soundbar. What should I do to get Dolby Atmos sound?

The LG-55LA620V was first released in 2013, which pre-dates Atmos support. Atmos support for HDMI-ARC didn’t show up until around 2018.
