No Sound in Starcraft II

Sound issues are almost always caused by incorrect settings or issues with sound peripherals.

1. Before doing any other troubleshooting, restart your computer. This can resolve numerous temporary issues
2. Check your Windows sound settings to ensure the right device is set as your sound output, and that the volume level is not at zero. There are several ways to reach the sound settings, including navigating Start > Settings > System > Sound
3. If your Windows settings are correct, check your in-game settings next. Ensure the right device is set to your output, that the volume levels are not at zero, and that the sound is not muted
4. If both Windows and Game settings are accurate, try another app with sound to see if the issue is with your headphones or speaker. If so, fully unplug your device and then plug it back in. Afterward, check its physical settings like volume knobs or mute buttons
