If you do not have any audio when you launch the game please make sure that your audio device is plugged in and enabled before launching Gauntlet.
If you still do not hear any audio, try updating your Audio drivers via your system or sound card manufacturer's website and then restarting your PC after the updated drivers have installed.
If you’re playing Gauntlet through Steam, make sure and verify the integrity of your game files.
To do so:
- Restart your computer and launch Steam
- From the Library section, right-click on the game and select Properties from the menu
- Select the Local files tab and click the Verify integrity of game files... button
- Steam will verify the game's files - this process may take several minutes
