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.

The HDMI standard does support surround sound ...
en.m.wikipedia.org/.../HDMI

I would check HDMI output setting on the xbox, there are 4 settings ... Stereo uncompressed, 5.1 uncompressed, 7.1 uncompressed, and Bitstream out. Try the x.1 settings and Bitstream setting to see if the receiver recognizes surround sound. If not, you will
likely need to use an optical cable to connect the Xbox to the receiver.

If you're using an Xbox One or One S (not sure on the One X) the only Dolby Atmos support is the Headset out jack on the Xbox controller.

The HDMI audio out options on the Xbox are located here -

- Settings > Display and Sound > Audio Output > (options) Off - Stereo uncompressed - 5.1 uncompressed - 7.1 uncompressed - Bitstream

You'll probably have to stick with Stereo uncompressed as the audio setting on the Xbox.

Based on page 14 of the manual of that sound bar, it only supports 2 channel input and it simulates 5.1 out

Yes I follow all the steps , actually netflix recognize dolby atmos content but any sound is produced by the soundbar

I'm not sure what you mean by "Yes I follow all the steps".

Have you got audio out from the Xbox and into your sound bar now?

No Xbox recognize my dolby atmos soundbar because i can setup in the audio settings uncompress audio bitstream and also I’m able to select home theater dolby atmos and then I’m able to open netflix and for example select the tv show content punisher and
The opción to select dolby atmos audio is able but nothing happens still no audio

The Xbox One or One S will not recognize the Dolby Atmos. That feature is for the Headset option on the controller only.

You state - "netflix recognize dolby atmos".

- Are you using the Netflix app built in to your TV?

Try this, run your HDMI OUT from the Xbox into the TV. And on the Xbox choose Stereo Uncompressed. See if the audio from the Xbox is working into the TV. I'm assuming you're running Out from the TV into your sound bar. After you have that done and the basic
stereo sound is working then change the other audio settings one at a time on the Xbox to 5.1 and 7.1 and then Bitstream and see what the TV passes through to your sound bar.

I can confirm the same issue happens to me. But if i use atmos on a windows 10 PC and can seamlessly switch between Atoms for headphones and the receiver without issues. That tells me that this is clearly possibly to do on the xbox one. Just a simiple matter
of cutting off the option connect when you choose.
