Setup

  • OS: Windows 10 Home
  • Sound card: Auzentech Prelude 7.1

(This issue might also apply to other Creative cards that have the Dolby Digital & DTS encoding features.)

Problem

When I try to enable Dolby Digital or DTS encoding using the Auzentech/Creative Control Panel or Console Launcher, I get the following error:

The audio format is not supported.

Here's what it looks like:

Audio Control Panel window showing the "Off" option with the error message next to it: "The audio format is not supported."

What I've tried

  • Using both Auzentech/Creative Control Panel and Console Launcher
  • Changing the number of speakers between 7.1, 5.1 and Headphones
  • Changing Windows' default output device from "Speakers" to "SPDIF Out"

You need to tell Windows that your digital receiver supports the Dolby Digital and/or DTS codecs:

  1. Open the SPDIF Out playback device's properties:

    Windows' Sound window showing SPDIF Out playback device

  2. Go to the Supported Formats tab and check the DTS Audio and Dolby Digital boxes:

    SPDIF Out Properties window on the Supported Formats tab showing DTS Audio and Dolby Digital checked
