Please connect external speakers to use DTS audio controls. Please connect a Headphone to use DTS audio controls.

- Right-click on it and select Update driver.
- Click on Browse my computer for drivers > Let me pick from a list of available drivers on my computer.
- Select the generic Microsoft driver or the Realtek driver (each OEM uses different drivers), then click Next.
After installing the correct driver, check if the issue persists.
3] Run Playing Audio Troubleshooter
