Hi! I understand you're having an issue where video plays fine on the Coverstar app but music won't play. Let's work through this together.

First, can you tell me if this happens with all videos or just specific ones? Also, have you noticed if the audio volume for music is muted or very low?

In the meantime, here are a few quick steps you can try on your iPhone (iOS 18.1.1):

1. Check App Permissions
Sometimes, the app may not have permission to access your device's microphone or audio features properly. Go to Settings > Coverstar and make sure all permissions (especially microphone and audio-related) are enabled.

2. Close Other Apps
Make sure no other apps that use audio are running in the background. Double-click the Home button or swipe up and hold to access the app switcher, then swipe away any other apps.

3. Restart Your Device
A simple restart can refresh system processes and fix strange audio glitches.

4. Update the App
Verify if there is an update for Coverstar in the App Store. Updates often include fixes for audio or video functionality.

5. Reinstall the App
If the problem persists, try deleting the Coverstar app and reinstalling it. This can clear corrupted app data that might be causing the music not to play.

If you’ve tried any of these steps already, please let me know which ones, and we can explore more advanced settings or look for other solutions.

Are you satisfied with these initial steps, or should we dive deeper?
