Question

dts:x hometheater speaker does not work and don't show enable option

Answer 1

Hi Nishant Chauhan,

I understand how inconvenient it is when “DTS:X for home theater” doesn’t appear or can’t be enabled, especially when you expect it to work with your speakers. Have you already tried the Q&A Assist suggestions? In addition, please try the following.

Step 1: Verify the connection type

• DTS:X for home theater requires an HDMI connection to an AVR / soundbar / TV.
• Analog (3.5mm) and Bluetooth connections do not support DTS:X for home theater.
• If you are currently using 3.5mm, USB audio, or Bluetooth, the option will not appear.

Step 2: Update the display/audio driver

• Open “Device Manager”
• Expand “Display adapters”
• Right‑click your GPU (Intel / NVIDIA / AMD) > “Update driver”
• Choose “Search automatically for drivers”

Step 3: Check HDMI device properties

• Open “Control Panel” > “Sound”
• Select your HDMI output device > “Properties”
• Go to the “Supported formats” tab. If DTS formats are not listed, the device or driver is not advertising DTS:X support to Windows

Step 4: Try a different HDMI port or cable

• Some TVs / AVRs only expose DTS:X on specific HDMI ports
• If possible, connect the PC directly to the AVR, not through the TV

Please clarify the following:

Do you connect your home theater to your PC via a standard audio connector (jack connector), HDMI, or digital optical cable (S/PDIF or TOSLINK)?

Is there an X in the speaker icon next to the clock?

Also, share a screenshot of your system information.

• Press "Windows + R", type msinfo32 and press Enter.

Maximize the window and use the shortcut "Windows + Shift + S" to use the screenshot tool.

Looking forward to your reply.

DTS:X for home theater appears only when both Windows and the connected audio device (AVR/soundbar/TV over HDMI) report support for that format. If the option does not show or cannot be enabled, use these checks:

1. Confirm the correct output device is selected
   1. Select the Speakers/Volume icon on the taskbar.
   2. Select the arrow next to the volume slider and choose the HDMI/AVR or soundbar device that should handle DTS:X.
2. Verify Windows sound settings and default device
   1. Open Control Panel.
   2. Go to Hardware and Sound > Sound.
   3. On the Playback tab, select the HDMI/AVR device and choose Set as Default Device, then OK.
3. Check spatial sound support on the device
   1. In Control Panel > Hardware and Sound > Sound, select the output device and click Device properties.
   2. Look for the Spatial sound section.
   3. If the device supports spatial sound, a Spatial sound format dropdown appears. Only formats actually supported by the device will be listed. If DTS:X for home theater is not listed, the current device/driver/connection is not exposing support for it.
4. Enable spatial sound from the taskbar (if available)
   1. Right-click the Volume icon in the taskbar.
   2. If the device supports spatial sound, an option to enable a spatial format (such as Dolby Atmos, DTS Headphone:X, Windows Sonic, or DTS:X) appears. If DTS:X is missing, it is not available for the current device.

If DTS:X for home theater still does not appear after selecting the correct HDMI device and checking spatial sound in Sound settings, the connected hardware or its Windows driver is not advertising DTS:X support to Windows, so the enable option will not be shown.
