Hi! I understand you're experiencing issues with no sound when playing or downloading with Parrot. Let's work together to resolve this.

To get started, could you please provide me with a little more detail? Are you using a specific app for playing or downloading content? Also, is this issue occurring with all media, or just certain files?

In the meantime, here are a few initial troubleshooting steps you can try:

1. Check Volume Settings: Ensure that the volume on your device (iPhone) is turned up. Sometimes, it's easy to overlook the physical volume buttons.

2. Restart the Device: A quick restart can often resolve temporary glitches. Hold down the power button and swipe to turn off, then turn it back on.

3. App Permissions: If you're using a specific app to play or download the content, check to make sure that the app has permission to access sound. You can check this in your iPhone settings under Privacy.

4. Update App: Ensure the app is updated to the latest version. Outdated versions can sometimes have bugs affecting performance.

5. Testing with Different Media: Try playing or downloading a different file to see if the issue persists. If it’s isolated to certain content, that might give us more insight.

Give these steps a try and let me know how it goes! If the issue continues, we'll dig deeper into more specific troubleshooting.
