What do you do when the sound on your ds is not working?

If the sound on your DS is not working, first check the volume settings to ensure it's turned up. Next, inspect the mute switch, if applicable, to confirm it’s not activated. If the issue persists, try resetting the device by turning it off and back on. If none of these steps resolve the problem, consider checking for software updates or consulting the user manual for further troubleshooting steps.
