Dolby Atmos Surround-System and Dolby Digital Headset

Hi Skorpion 111196,

Thank you for clarifying. Upon further research, I found that the mix amp you have made by Astro produces sound in the digital format of Dolby Digital Audio, which is different than Dolby Atmos, which is a surround sound technology engineered by Dolby to
have a virtual surround sound experience with any headset that you may use. Since your headset includes the mix amp, you only have to make sure you set it up exactly like the video and make sure the button is turned on the mix amp that allows the Dolby Digital
Audio. Dolby Atmos would not be necessary unless you plan on not using the mix amp. I suggest looking online for other threads that have people who are experts or know more about the technicalities of the differences between Dolby Digital and Dolby Atmos.

So for the 1st time last night after powering up my XBOX one X console, I noticed that when I plugged my headset in to my controller ( post boot up) that the Dolby Atmos app immediately opened without me manually activating it and ran a new and different
series of connection protocols which allowed the Dolby Atmos surround feature to be enabled.

I will also note that I have not received any confirmation reply back from NACON or Dolby Atmos., and when I powered up my console today with my headset already plugged into my controller prior to boot up that the default sound system was finally correct
for the 1st time in many months at "Dolby Atmo surround" setting instead of the default "Windows Sonic". I will also be tracking this over the next few days to see if it continues to boot up in the atmos surround feature for my headset correctly and consistently.

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!

The Xbox audio settings I have available are as follows:

HDMI audio:

* Stereo Uncompressed

* Dolby Digital

* Dolby Atmos for Home Theater

Headset Format:

* Stereo Uncompressed

* Windows Sonic for Headphones

* Dolby Atmos for Headphones

* DTS Headphone:X

Tried all of them. Nothing helped.

Hi bladerunnin,

Thank you for posting on the Xbox Forums.

The reason you need to unplug the base station if you want to use Dolby Atmos for Home Theater is in the way the Dolby Atmos sound format is processed within the Xbox and Dolby Digital 7.1 in the A50's and DTS 7.1 in the TB 800X respectively.

The Dolby Atmos sound format for Home Theater on any platform is processed in the device itself through HDMI, in this case the Xbox's operating system and software. The Xbox will decode the audio in a bitstream format through HDMI for Dolby Atmos HT. The
headset base stations (not the Xbox) process and decode the audio formats and then send the data to the Xbox in bitstream through optical. Since everything is processed through the base stations for the headsets, simply turning off the headset won't remove
the base station as a device that is hooked up and recognized by the console, at least while the audio settings in the Xbox are still set for Optical audio: Bitstream out. That may be why you are getting the message that Dolby Atmos is only supported over
HDMI.

Under Speaker audio in the Audio output settings of the Xbox, try turning off Optical audio while leaving HDMI audio on Bitstream out, then under Bitstream format select Dolby Atmos for HT. When wanting to use the headsets, turn off HDMI audio and then put
Optical audio on Bitstream out, then under the format choose Dolby Digital (Astro A50) or DTS Surround (TB Elite 800X). If you have tried that but still can't enable Dolby Atmos while you have everything plugged in, then just disconnect the optical cable but
leave the USB plugged in, which is what charges the headset, not the optical cable.
