I have the following setup:

-Sony bravia kd65xd8505 with Arc output high speed wire

-Apple TV 4K - Netflix upgrade to 4K

-Sonos Arc with two Sonos Ones  + Subwoofer setup all in network  sonos boost

Sonos connected via wi-Fi from boost

Arc connected to Tv via hdmi 


So my problem is no atmos sound at all

I have only Dolby 5.1 and Vision. 



How can I resolve this problem?

As far as I can see this TV is from 2016. Are you sure the TV or the apps featured on it are Atmos capable? Since it does not have eARC you would only get Atmos from DD+ sources.

If the apps are Atmos capable, I'd look at the sound settings on the TV (look for pass through or Atmos).

@WN77 From Apple’s website:

“Apple TV 4K uses a high bandwidth form of Dolby Atmos that doesn’t work over ARC connections.”

Your TV is only equipped with HDMI ARC not eARC.

To bypass your TV’s limitations and get Dolby Atmos from your Apple TV, you could get the HDFury Arcana. I have one and it works great:


@GuitarSuperstar thank you for help. I’ll order this ASAP
