Any word at all on Dolby Atmos audio lag?

If the game does not support Dolby Atmos, then the audio is normal stereo. Microsoft are working on updating Dolby Atmos, where if the game does not support Dolby, the audio will be converted to simulate Dolby Atmos.

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).

Hey Diego,

Thanks a lot for the prompt reply. I appreciate you taking time to explain how the audio signal is processed by the various devices in my chain. I just got home and was able to try your suggestions...

It doesn't work.

Once the base station is connected to the Xbox via USB, Dolby Atmos is automatically disabled and cannot be re-enabled no matter what settings I apply. My Audio Output settings are:

- HDMI Audio -> Bitstream Out

- Optical Audio -> Off

- Bitstream Format ->Any attempt to select Dolby Atmos yields the message "For Dolby Atmos for Home Theater, you need to be using HDMI. Dolby Atmos for HT only supports HDMI devices. Try unplugging any headsets or optical headset base stations." and both
DTS and Dolby Digital are selectable.

In other words, turning Optical Audio to OFF does not make the Xbox ignore the base station...so Atmos is still not useable.

Your suggestion makes perfect logical sense and that is exactly how it should work. But the Xbox doesn't seem to behave logically in this instance.

Do you have any other advice?

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 RomiDumitru,

*maybe* this "problem" is exactly how the Dolby Atmos App on Xbox One X works.

Dolby Atmos native content? perfect! Dolby Atmos playback.

No Dolby Atmos? the App upmix current audio track to Dolby Atmos (the headphones features works in this way).

I don't know if is intentional.

So after following up with the Dolby Access support team, apparently games aren't supported on home theater, only on headphones:

"Unfortunately, Games encoded with Dolby Atmos audio are not compatible with Dolby Atmos for Home Theater, as they are specifically configured for Dolby Atmos for Headphones. If the content you are experiencing is not compatible with the app you are
using, then audio will cease, or will simply output as regular stereo output.

To clarify, Dolby Atmos for Home Theater is included at no charge with any Dolby Atmos supported hardware, such as a receiver or Xbox One X, and is used to activate Dolby Atmos features via HDMI connection for a Dolby Atmos certified AVR, soundbar,
or TV."

"Unfortunately, the version of Dolby Atmos included with your Xbox is Dolby Atmos for Home Theater, which is not compliant with any gaming content."

It kind of strikes me as hard to believe, or that this won't be addressed, but that's what they're saying for now. That said, it still isn't working for me for Netflix content either, so I'm going continue troubleshooting with them and see what's doable
and what's not. Fingers crossed.
