BT Box Pro Dolby Atmos issue

[LowestoftBoy]

No Dolby Atmos when watching live football on BT Ultimate via wifi, even though running through an Onkyo Atmos receiver. No atmos either on Netflix app. My old BT 4k box decoded atmos just fine for BT Ultimate and Netflix. My Apple TV 4k decodes BT Ultimate Atmos just fine, but I prefer to use BT Box Pro as the Apple TV picture sometimes has problems on BT Ultimate. All software updated. Is there a known issue and a possible fix?

It would appear to be either a set-up or settings issue as we have a Pro Box and it puts Atmos through fine. I'm going HDMI to the TV and then HDMI out via eARC to my Soundbar.. TV audio is set to pass through and Pro Box just set to Surround. Pro Box is hardwired to the Smarthub...

All HDMI cables are 2.1

Thanks for the suggestions.

Well, my BT box passes through my receiver, as does my Blu ray and apple tv, both of which my receiver recognises the atmos. I guess the BT box just doesn't play ball with a 2018 Onkyo atmos receiver. Oh well.

Check the HDMI cablefrom the BT box is 2.1 standard

Brain Fart: I think I just posted this in the wrong Community, trying to reply to :-https://community.ee.co.uk/t5/TV/TV-Box-Pro-amp-Dolby-Atmos/m-p/1463729#M5647

But I’ll let it stand, and link across.

I just put on the Apple TV app on my Box Mini should be same as Box Pro here), went to Slow Horses S4, E6, which is shown as having Dolby Atmos, played it, and my soundbar confirms the Atmos (I press Info, it just scrolls DOLBY ATMOS and goes back to ‘eARC’, so kind of hard to snapshot, but you can see Y ATM going by on the soundbar, at bottom):-

So the Box can do the advertised Dolby Atmos; your question now is why there is no Dolby Atmos where you expect it, maybe because what you are playing doesn’t offer it, or the subscription you have it on doesn’t run to it?

Can you try my above recipe, see what you get? Hopefully, we are all the lucky beneficiaries of a free Apple subscription at the moment.

@Midnight_Voice are you getting UHD HDR on AppleTV via the Pro Box?

There was an issue on Sky Stream where AppleTV was defaulting to Dolby Vision and if it couldn't detect a compatible device, it'd fall back to HD and no Atmos rather than outputting HDR10 with Atmos. It was picked up pretty quickly and a fix was issued which I imagine was an update to the app.

I’ll have a look tomorrow if I get a chance.

For various reasons, the Box Pro is connected to the bedroom LG OLED48C2, which is quite decadent enough without adding a soundbar, and throws the sound round the room remarkably well anyway, so the above Atmos test had to be on the downstairs LG OLED65GX setup.

But I can check both tomorrow for your question about the video.

Box Mini here, but yes, you can see the momentary HDR indicator top right in this screenshot:-

I don't have BT TV anymore as we moved to Sky last year. 

Can you receive Atmos through other streaming platforms?

@NigelB72 

Well, the above Atmos example was from Apple TV on the Box Pro. So it’s a fair bet that Apple TV on the Apple TV+ box will do it, and it will work on many other platforms that have the Apple TV app.

But your question is very wide-ranging. What platforms are you thinking of?
