If you no longer hear any in-game sounds or if they are glitched, there are a few troubleshooting steps you can take:
- Force-close Bowling Crew so that it is not running in the background, then launch it again;
- Check the game's settings: both Music and Sound should be ON. If they are, try switching them OFF, then back ON;
- If your earphones are plugged in, try unplugging them;
- Make sure silent mode is not enabled on your device;
- Reboot your device.
If none of these steps helped you resolve the issue, please contact Support.
