Decoding Dolby HD Atmos 7.1?

Apparently dolby atmos will only transfer through hdmi and not optical,i was just wondering whether it is something to do with hdr

Do you have "let receiver decode audio" enabled in Settings > Disc & Blu Ray > Blu ray?

And after that go to Settings > Display & Sound and go, under HDMI audio, to Bitstream format and select "Dolby Atmos for home theater".

After doing this the blue light for Dolby Atmos should be lit on your receiver when it is decoding Dolby Atmos input.

Thanks for the reply Brad. I can confirm that dolby digital produces 5.1/7.1 the issue centres around Dolby Atmos and its ability to downsample a non atmos track.

Hello D3mondkid12! Dolby Digital is a system that designates 2.0 up to 5.1 or more channels where the speakers are arranged horizontally (designations include Dolby Digital, Dolby Digital EX, Dolby Digital
Plus) Dolby TrueHD is the next step but the speakers are still arranged horizontally.

Dolby Atmos is a system where speakers are arranged both horizontally and vertically. Examples include 3.1.2, 5.1.2, 5.1.4, 7.1.2, 7.1.4. The first number is the number of horizontal speakers, the second number
is the subwoofer, and the third number is the number of vertical speakers (vertical speakers can be placed on the ceiling or pointing up from the top of the horizontal speakers). Dolby Atmos information can be encoded within a Dolby True HD signal - if you
have a Dolby Atmos Blu-ray and your receiver doesn’t feature Dolby Atmos decoding, it will default to Dolby TrueHD, Hope it helps!

Hi

I have the same problem like you. I have an Xbox One X connected through HDMI cable to an Onkyo amplituner 7.1 which is capable to decode Dolby Atmos & DTS X.

I have installed Dolby app on my Xbox to get Dolby atmos sound and the result was that I have on all the games no matter if these are with sound in Dolby Atmos or not only in Dolby Atmos.

Is very strange to get that. I have supposed that when I buy a game with sound in Dolby Digital 5.1 to have Dolby Digital 5.1 and when I buy games in Dolby Atmos to get Dolby Atmos in my amplituner Onkyo.

The same problem I have with all the movies from Netflix. I installed the Netflix app on my Xbox One X and now all the movies I see have sound in Dolby Atmos, even if in the name of the movie on Netflix it is said the sound is recorded only in Dolby Digital
5.1.

What to do in that situation ?......I have tried every settings on my Xbox without any result.......When I put settings on output sound in Xbox everything I played is all in Atmos.

Like you said: "We don't need everything to be upscaled to Atmos, we just want Atmos to work on stuff that is Atmos as it should!"

Thanks in advance for everybody give me every piece of advice

[quote user="NanoTechSoldier"]You are seriously NOT getting it,[/quote]You keep saying that. I "get" how the MixAmp works just fine.

The Source might encode Dolby 7.1 Surround for Multiple Speakers, BUT.. It is Matrix Encoded/Decoded,

Dolby
Digital? No, Dolby Digital is discrete channels. Dolby Surround is matrixed.

on the Astro MixAmp, for playback of 7.1 channels of a 2 channel Headset...

No, there is no Encoding on the MixAmp. There's decoding and processing, that's it
