Hello! I understand that you’re experiencing a no sound issue with the Islam360 app on your device. Let’s get to the bottom of this together.

To start, could you please let me know a bit more? For example:
- Is the app failing to play any audio at all, like Quran recitations or notifications?
- Have you checked whether your device’s overall sound is functioning fine with other apps or media?
- Are you using any headphones or external speakers?
- Have you recently updated the app or your Windows system?

Meanwhile, here are some basic steps you can try to troubleshoot the no sound issue on Islam360 running on Windows 10 with WebKit browser environment:

1. Check System Volume and Mute Settings:
- Look at the Windows taskbar volume icon and ensure the sound is not muted or too low.
- Also check if the app is not muted specifically by clicking the volume mixer (right-click volume icon > Open volume mixer) and confirming Islam360 app’s volume slider is up.

2. Restart the Application:
- Completely close the Islam360 app and reopen it. Sometimes apps need a fresh start to reset audio processes.

3. Ensure Windows Sound Settings are Correct:
- Right-click the speaker icon in the taskbar > Open Sound settings > verify correct Output device is selected (your speakers or headphones).
- Test sound with the "Test" button to rule out device issues.

4. Update the App and Windows:
- Make sure you have the latest version of Islam360 installed from their official source (theislam360.com).
- Run Windows Update to ensure system components that affect audio are up to date.

5. Check App Permissions:
- Go to Windows Settings > Privacy > Microphone or other media permissions and check Islam360 has needed permissions (even though this is mainly for recording sound, sometimes media access rights help).

If after these steps the sound issue persists, let me know what you have already tried or noticed, and I can guide you through some advanced troubleshooting.

Are you satisfied with the initial solution I provided, or would you like me to help you dig deeper?
