How to get Dolby Atmos from TV without eARC?

Hi,

I am setting up a new Sonos-system with Arc, 2xETA300 and Sub. My Sony-TV only has HDMI with ARC, not eARC and therefore I only get 5.1 to the soundbar. I use Netflix and Viaplay on a AppleTV (4K).

My question is: Is it possible to get Atmos to the soundbar with this equipment? I see that some people says that the Hdfury Arcana-adapter will solve this, has anyone in the forum tried this?

Ah, there is a point. There are two kinds of Atmos signal, one that can be carried on an ARC connection via Dolby Digital Plus, and another (uncompressed) that requires an eARC connection. 
 

I’m not a Netflix subscriber, but I’m fairly confident they do the former, not the latter, so you wouldn’t need to get the external eARC device such as the HDFury, assuming that TV can pass a Dolby Digital Plus signal. Apple TV, on the other hand, uses MAT, which contains the uncompressed version of Atmos, and would most often require an external device.

There are quite a few threads about this. 
 

Here is a cut and paste about some data:

There is the HD Fury Arcana, the Feintech VAX04101k, and the latest, is the OREI HDA-935. You can also order from those links from the companies directly, or check your local retailers for availability. Amazon may carry some, depending on location.
 

Note that there is now a HDFury Arcana 2, and likely some other providers of similar hardware that extract the audio signal before it reaches your TV.

    @Thor-Egil What exact model TV do you have?

    There are a few TV models without eARC that can play Dolby Atmos audio from an Apple TV 4K. Try these settings on your TV and test an Atmos film on Netflix on the Apple TV:

    Digital Audio Out: Auto 1

    Dolby Digital Plus Output: Dolby Digital Plus

    Pass Through Mode: Auto

      Thanks for your answers! I have ordered an Arcana-adapter, hopefully this will be a good solution :-)
