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.

You should also be aware that the Play 1 does not support Dolby Atmos.

Since your TV is the limiting factor here, buy a new TV or look at a device that takes the TV out of the equation, like the HD Fury Arcana, the Feintech VAX04101k, or the OREI HDA-935

Thx! that is true, after googling this, now I know the difference between HDMI ARC and HDMI eARC. Even the passthrough is not possible. 

 

I need to buy a new TV.

For Atmos eARC isn’t always necessary. Most content services use a (compressed) DD+ stream with Atmos, that can be sent via ARC. You’d only need eARC for uncompressed streams, from a BD-player or Apple TV for example.

This will not help you because Atmos wasn’t around on TV’s when it was made.

Perfect timing for new TV shopping, I just got my first batch of early Black Friday deals ads, Sonos and a bunch of others.

25% off a Sonos theater combo set is a pretty sweet deal.

Spouse has firmly said there will be no 100 inch TV in our living room, one won't fit in my office. So sad.
