A:Answer Thank you for your question! Dolby Atmos support is available for Xbox games, streaming apps, and 4K Ultra Blu-ray discs. You'll need a Dolby Atmos-enabled TV, soundbar, or home theater system — or you can activate Dolby Atmos for Headphones on your Xbox or Windows 10 PC (available for purchase or with select gaming headsets).
Enable Dolby Atmos through the Xbox Audio settings page:
Press the Xbox button to open the guide and select Profile & system > Settings > General > Volume & audio output.
Under HDMI audio, select Bitstream out. Under Bitstream format, select Dolby Atmos for home theater
