Hi there! I see you’re having trouble with audio not working on the Sight Reading Factory app. I’d like to help get this sorted for you. To start, could you tell me a bit more about what’s happening? For example:

- Are you not hearing any sound at all, or is the sound distorted or out of sync?
- Is this issue happening on all exercises or just specific ones?
- Do you use external speakers, headphones, or your computer’s built-in audio?
- Have you noticed any error messages like a "Playback Synchronization" warning?

Knowing this will help me guide you better. In the meantime, here’s a general step-by-step to troubleshoot audio issues with Sight Reading Factory on Windows 10 using a WebKit-based browser:

1. Check Basic Audio Settings:
- Ensure your device volume isn’t muted or too low.
- Check if other websites or apps produce sound correctly to rule out a system-wide issue.

2. Browser and Tab Check:
- Make sure the browser tab running Sight Reading Factory isn’t muted. Right-click the tab to check.
- Try refreshing the page or restarting the browser.

3. Update or Switch Browsers:
- Although you use a WebKit browser, Sight Reading Factory works best on updated browsers like Chrome, Firefox, or Edge. Make sure your browser is up to date.

4. Audio Permissions:
- Confirm that your browser has permission to use audio devices, especially if you’re recording or using playback features.

5. Playback Synchronization Warning:
- Sight Reading Factory sometimes uses audio cues (prep beats) to synchronize playback. If you get a "Playback Synchronization" warning, it may affect audio output. This could be temporarily disabled in settings or needs a reload.

6. Clear Cache and Cookies:
- Sometimes clearing your browser’s cache and cookies can solve unexpected audio issues.

7. External Audio Device Check:
- If you use headphones or external speakers, disconnect and reconnect them.
- Try switching to a different audio device to see if that fixes the problem.

If you’ve tried any of these or if you have more details about what you’re experiencing, let me know! I can guide you through more specific fixes or advanced troubleshooting next.

Are you able to share more about the exact behavior of the audio problem?
