Hi there! I understand you're having trouble with no sound in the Stealth Master app on your iPhone running iOS 15.7.8. To help you better, could you tell me if the app itself is completely silent (no sounds at all) or if the issue is only with certain aspects like background music, effects, or voice?

Also, are you using headphones, Bluetooth speakers, or playing sound through the iPhone's built-in speakers? Any extra detail can help me find the right fix for you.

It’s completely silent

Thanks for the details! Since the Stealth Master app is completely silent on your iPhone, let's try a few straightforward troubleshooting steps to isolate the problem:

1. Check iPhone Silent Mode and Volume:
- Make sure the iPhone’s physical mute switch (on the left side) is not set to silent (orange visible).
- Press the volume up button a few times to increase the sound.
- Also, try playing another app with sound, like Music or YouTube, to confirm the phone speaker works properly.

2. In-App Sound Settings:
- Open Stealth Master and look for any sound or volume settings within the game menu. Sometimes, apps have their own audio controls which might be muted.

3. App Permissions:
- Go to Settings > Stealth Master, and ensure it has permission to access sound or microphone, if listed.

4. Restart the App and Device:
- Fully close Stealth Master by swiping it away in the app switcher, then reopen it.
- If that doesn’t work, restart your iPhone.

5. Reinstall the App:
- If sound is still not working, try uninstalling and reinstalling Stealth Master from the App Store. This can resolve corrupted files affecting audio.

6. Update iOS and App:
- Ensure your iOS 15.7.8 is up-to-date with any minor updates available.
- Check if Stealth Master has a newer version available and update if so.

If you’ve already tried any of these steps, please let me know which ones so I can offer more advanced options. Otherwise, this usually resolves the silence issue.

Are you able to access any sound settings in the app, or can you confirm the other apps on your phone have sound normally?
