Are you having trouble getting Todo Math or another game to produce sound even though your device's volume is turned up?
Don't worry — there's a simple fix! When this happens, it often means that your device is muted. The mute feature on a phone or tablet means that it won't make sounds (ringing, notifications, etc.), but it can sometimes interfere with the sound input from various apps.
If your volume is turned up, just unmute your device and this should fix the problem.
