Hello! I see you're having some trouble with the KaraFun app on your Android device where there's no sound in play or queue mode. Let’s work together to get this resolved.

Could you tell me a bit more about when this started happening? Did you make any changes to your device or the app before the sound stopped working?

In the meantime, let’s try a few basic troubleshooting steps:

1. Check the Volume Levels: First, ensure that the volume on your device is turned up. Sometimes the app volume can be muted or set very low.

2. App Permissions: Make sure that the KaraFun app has the necessary permissions on your device. Go to your device settings, find Apps or Applications, select KaraFun, and ensure that permissions for audio are enabled.

3. Restart the App: Close the KaraFun app completely and reopen it to see if that resolves the sound issue.

4. Clear Cache: You might also want to clear the app's cache. You can do this by going to your device settings, then to Apps, selecting KaraFun, and choosing 'Clear Cache'.

If you've tried these steps and still hear no sound, you might want to check if other apps on your device can play sound. This will help us know if the issue is with the app specifically or your device more generally.

Let me know how it goes!
