To forward the AppleTV atmos mat signal you will need an eARC connection. So that’s the reason why it doesn’t work.

But congrats your old TV seems to be able to handle compressed DD+ based atmos via ARC. 😎👍🏻

Thank you for this advice, very useful. Assuming I want to keep costs down and keep my tv, which HD fury product would be best for 3 inputs (virgin tv, Apple TV and dvd) whilst outputting to the TV and passing atmos signals to the arc ultra?

For three inputs costs will be the highest if going with the hd fury, because itself it is quite expensive and also it supports just one source input. So you would need an additional hdmi switch as a second device. 
 

Take a look at the FeinTech VAX 04101 or the new AX340. They have 3 / 4 source inputs. I have both and they work quite good. 
The problem is that FeinTech (they are from Germany as me too… 😉) does not deliver out of the EU. But there are possibilities to order their products on Amazon with option of delivery out of the EU. 
For the VAX04101 their is an identical device of another brand called OREI. They sell from the US as far as I know.

Oh, I really don’t care about Big Brother regarding AI. Imo it’s the same with Alexa the last years. 😂

My doubts are similar like those ​@jgatie mentioned. I think depending on how exactly you ask, the answer of AI can be somewhat misleading.

Weirdly and only whilst watching Disney+ via Virgin box, my Sonos is reporting an Atmos signal. This is not the case if I do the same with Apple TV, I can only get pcm 2.0

could my hdmi cables be playing a part in the problem here?

In the Apple settings, under Audio Format, have you got Dolby Atmos set to On?

(But it may be that the Virgin box sends Dolby Atmos via Dolby Digital Plus, which the HDMI ARC port can handle. I don’t think the uncompressed Dolby Atmos sent by the Apple TV box will work for you).

All as described earlier.

FWIW, it isn’t an impossibility for the HDMI cables to be too old (wrong HDMI version) to carry the Dolby Digital (Atmos) signal. You might want to double check them, they should be at least HDMI version 1.4 or higher to work. Older ‘versions’ won’t carry the signal.
