No. DTS:X for Home Theater is a free upgrade on Xbox One S, Xbox One X, Xbox Series S, and Xbox Series X. Simply install the DTS Sound Unbound application from the Microsoft Store on your Xbox to get started. Once installed, DTS Sound Unbound unlocks the DTS:X for Home Theater setting in your Xbox system audio bitstream settings.
How do I turn on DTS:X for Home Theater?
On your Xbox, navigate to [Settings > General > Volume & audio output] and select [Bitstream out] as your [HDMI audio] preference. Then, under [Bitstream format], select [DTS:X for Home Theater]. If selecting DTS:X for Home Theater for the first time, you will be prompted to download and install the free DTS Sound Unbound application. Once installed, DTS:X for Home Theater is ready to go! Don’t forget to verify that your sound bar or home theater receiver also supports DTS:X. Contact your sound bar or home theater receiver manufacturer for details.
How do I know if my home theater system supports DTS:X?
To verify whether or not your home theater system supports DTS:X, check the product packaging or included product manuals for the DTS:X logo. If you’re still not sure, contact the manufacturer of your sound bar or home theater receiver and ask if your particular model supports DTS:X. Finally, be sure to install the latest available firmware on your sound bar or home theater receiver for the most up-to-date features and compatibility.
Why don’t I hear sound from my Xbox when DTS:X for Home Theater is selected?
First, confirm that you’ve selected the HDMI input on your home theater system into which your Xbox is connected. Next, play a game and turn up the volume on your home theater system. If you’re still not hearing any audio, a firmware update may be required. Please contact your sound bar or home theater receiver manufacturer for assistance. Alternatively, many sound bars and home theater receivers can connect wirelessly to the internet and receive firmware updates.
I’ve connected the Xbox directly to my TV with HDMI. Can I still use DTS:X for Home Theater?
DTS:X is a lossless audio bitstream technology that requires a high-bandwidth connection between your television and home theater system. With that in mind, only televisions supporting eARC (enhanced Audio Return Channel) over HDMI are compatible with DTS:X. Additionally, your sound bar or home theater receiver must also support eARC over HDMI. Using a high-bandwidth HDMI cable, connect your home theater system to your television ensuring that both ends are connected to the HDMI input labeled eARC. Once connected, ensure that your television is set to output audio over eARC. If additional assistance is required, please contact your television manufacturer.
Why isn’t sound coming from all of my speakers?
DTS:X for Home Theater delivers audio in its original channel configuration from the Xbox to your sound bar or multi-channel home theater system. If the source material, such as a movie, was encoded without audio in the height speakers, your height speakers will remain silent during playback.
Why isn’t my DTS Gaming Headphone unlocking DTS Headphone:X?
Gaming headphones that integrate DTS Headphone:X v2.0 or PC products that integrate DTS:X Ultra will automatically license these DTS Headphone:X and DTS:X products that support Microsoft Spatial sound.
Gaming headphones and PC products that integrate DTS Headphone:X (not ‘v2.0’) will require the additional in-app purchase to unlock DTS audio for Microsoft Spatial sound.
