Hi there! I see you're having trouble with sound not working on the Online Radio Box app on your Windows 10 device. Let's work together to figure this out.

To start, could you tell me:
- Are you using the Online Radio Box app or the website on a browser?
- Is this issue happening with all radio stations, or just specific ones?
- Do you have other sounds playing fine on your device normally (like music or system sounds)?
- Have you already tried any fixes like checking volume settings or restarting the app?

Meanwhile, here are some basic steps we can try to resolve "no sound" issues on Windows for Online Radio Box:

1. Check System Volume and App Volume:
- Click the speaker icon on your taskbar and ensure volume isn't muted or very low.
- Right-click the speaker icon > Open Volume Mixer, and check if Online Radio Box or your browser is muted there.

2. Check Playback Device:
- Right-click the speaker icon > Sounds > Playback tab.
- Confirm the correct audio output device (speakers/headphones) is selected and enabled.

3. Restart the App or Browser:
- Close the Online Radio Box app or browser completely, then reopen and try again.

4. Try Another Station or Stream:
- Sometimes specific station streams can have issues, so try a different station to rule that out.

5. Check for Windows Sound Settings:
- Settings > System > Sound > Advanced sound options > App volume and device preferences. Make sure the app is set to the right output.

6. Update Audio Drivers:
- Outdated or corrupted audio drivers can cause sound issues. You can update this via Device Manager > Sound, video and game controllers > your audio device > Update driver.

Could you try these and let me know if anything changes? That will help me guide you further!
