You can't use a dolby Atmos enabled sound bar while also having a headset base station BUG.

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 optical cable does not trigger the Xbox to see the base station...it's the USB cable that - when connected - prompts the Xbox to recognize the presence of the base station/headset and disables Atmos. So it's not possible to charge the headset and use
Atmos.

The optical cable can stay plugged in at all times and does not effect the ability to enable Atmos.

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.

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.

If you have a sound bar that supports Dolby Atmos, then it wont cost you anything to use it, only the headset portion of Dolby Atmos is $14.99. I use Dolby Atmos and it does sound great, but only for games that support it, otherwise it just sounds normal
for the games that don't.

Is the xbox connected directly to the sound bar?

Have you also checked that dolby atmos is enabled on that soundbar?
