If Mr Stump's Dentures plays fine but you hear nothing, the cause is almost always outside the game itself.

Checklist

• In-game audio. Make sure the sound is not muted in the game's options or pause menu. See The music and sound.
• System volume. Confirm Windows volume is up and the game is not muted in the Windows volume mixer.
• Output device. Check that the correct speakers or headphones are selected as your default playback device.
• Other apps. Verify sound works in another program; if nothing has audio, it is a system problem, not the game.

If audio works everywhere except in the game, let us know your Windows version and audio setup.
