Re: BT Box Pro Dolby Atmos issue

Netflix via Apple TV. Dolby Atmos works fine through Onkyo 696.

TNT sports ultimate via Apple TV, where matches are advertised as Dolby Atmos will not decode atmos through that same Onkyo receiver.

A bit annoying.

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?


As far as I know the EETV Box Pro always outputs in DD+ when in surround mode, so regardless of whether the source is stereo, multichannel, atmos or whatever,  your AVR will say DD+, thats what my Denon AVFORGOTMODELNUMBER says. However if I use my Apple TV Box then yes I can see Atmos pop up on my Receiver.

So indeed, whenever I watched TNT Sports Ultimate channel my AV just shows DD+. If you bring up the AVR OSD you can usually check what channels are actually active. For example on the Denon app if all channels are active:

If they are not all active just stereo (FRFL) will be in green but the sound mode will still say DD+. I have deduced from this that even if TNT Sports Ultimate via the EPG is presented in Atmos, my AV will still show DD+, like it does for any channel.

How do you explain my posting 23-10-2024 15h13 higher up in this thread, then?

Re: BT Box Pro Dolby Atmos issue

It’s actually really hard to explain mate and it’s mostly down to poor implementation of the audio on the EETV Box Pro where it doesn’t actually pass through the source audio and packages everything up in DD+, so your AVR wont switch to Stereo when watching BBCOne (which is definitely not DD+) and won’t switch to Multi Channel when watching Sky Sports (Which is not DD+), at the same time an AVR won’t then pickup when the Atmos is there on top of multi channel. ATMOS when delivered via the DD+ is lossy, when delivered with TrueHD it’s lossless, the latter seems to be picked up without fail on AVR’s.

Lets get this out the way….yes it’s possible, here’s me watching a recording of City vs Sparta Prague:

It’s problematic more for AVR’s, as far as I remember you use eARC assuming the TV passes audio through to the sound bar. Probably works better that way with EETV.

The OP might be able to use ATMOS on his AVR if he manually changes the audio mode when he knows ATMOS is there, it’s possible for me. But it’s largely pointless if you don’t have the relevant atmos speakers so might as well just stick with the DD+ for all channels which offers the best audio sync.

On my other devices where I’m using Lossless TrueHD it seems to switch to Atmos fine recognising it, or on devices that just play the source audio and not uniformly package it in one codec, probably a compatibility thing, but the OP may have some joy if when watching Atmos content on the box he cycles through the audio modes and manually locates Atmos. Problem is most of us just want the audio device to just switch automatically to the relevant mode but the EETV makes this problematic given the way it by default delivers audio when in surround mode….via DD+ even if only two channels are present. It should just deliver stereo PCM or something and then Dolby Digital when the source is such not confusing your AVR. But using DD+ is I’m sure an easy way to deliver all audio in one format, simplifies delivery but complicates things at our end.

This is just my take from my experience trying to explain it.

Re: BT Box Pro Dolby Atmos issue

@naylor2006 

So what you are saying is your poncy amp spurns lossy Atmos over DD+ and only gets out of bed for TrueHD Atmos, while my simple soundbar doesn’t know any better and latches on to any flicker of Atmos? 😛

I am told, by the way, that Atmos isn’t all about height, but about pinpointing sounds left and right, front and rear, in a rather superior way to panpotting.

So while height is a nice addition, even those without upward firing speakers can benefit from Atmos; and to a lesser extent still, even those without rears.

Re: BT Box Pro Dolby Atmos issue

Yes, I have the atmos speakers. 

Focal Sib Evo. Very happy with it. 

Went with the Onkyo 68 tx-nr 696 over a soundbar so as to put my cd, phono, spotify etc through it. It is great for music with just the left, right and sub.

Thanks for all the well informed replies, folks

Re: BT Box Pro Dolby Atmos issue

 

Thanks for that retort, you’ve already made my weekend 😂

Yes the soundbar wins in this ease of use scenario, you win Mr Vocal.

You are kinda right yeah, but it’s more that the EETV box isn’t providing a definitive change between audio sources. If it when it went from DD+ to TrueHD with Atmos it would change. For example Dolby Atmos on Apple TV Plus on an Apple TV is still lossy but there are relevant and definitive changes between audio sources when moving between apps.

The AVR is being too clever or too dumb, but definitely poncy 😂

There are some other notes on this as well with regards to DD+ Plus Surround settings (I meant to write + and Plus) but it’s a nuanced AVR thing and the vast majority of folks get on perfectly fine with ARC and probably not using an AVR with the EETV Pro so I’ll save it for another day. But that setting allows for the auto changing but has other annoying compromises on audio that isn’t Atmos 😕

Its a mess and sometimes with AVR’s you have to find the best most consistent setting you can just leave alone.
