THX Spatial Audio is an audio enhancement and tuning utility available as a premium purchase for all Windows devices. However, the audio enhancer can run into issues and stop working, leaving you with no sound.

If you experience no sound from THX Spatial Audio, it can be due to an incorrectly configured default playback device or incompatibility issues. Here are a few troubleshooting steps to help you fix this problem and get THX Spatial Audio working again.

1. Run the Windows Audio Troubleshooter

The Windows Audio troubleshooter can find and fix common audio issues with the system's sound and audio devices. For instance, it should be one of your first ports of call if you want to fix no audio on Windows 11.

The troubleshooter will scan the system for issues and then recommend fixes accordingly.

To run the Windows Audio troubleshooter:

  1. Press Win + I to open Windows Settings.
