Hi there! I understand you're experiencing some issues with the sound disappearing while using Loyal Books. Let’s work together to narrow down the potential causes and find a solution.

First, could you let me know:
1. Is this happening with all audiobooks or just specific titles?
2. Are you using headphones or the device's speakers?
3. Have you noticed if the issue happens at a certain point in the audio or is it random?

With a bit more detail, we can start troubleshooting effectively!

It happens with all programs

Thank you for the additional information! Since the sound issues occur across all programs on your Mac, it sounds like it could be related to the system settings or audio hardware. Let’s troubleshoot this together.

Here are some steps to follow:

1. Check the Volume Levels: Make sure the volume is turned up on your Mac. You can do this by clicking the volume icon on the top right of your screen and adjusting the slider.

2. Sound Preferences:
- Click on the Apple menu at the top left corner of your screen.
- Select "System Preferences."
- Click on "Sound," then the "Output" tab. Make sure the correct output device (like internal speakers or headphones) is selected, and that the sound is not muted.

3. Audio MIDI Setup:
- Go to "Applications" > "Utilities" > "Audio MIDI Setup."
- Check that the correct audio output format is selected for your device and that it is configured properly.

4. Restart Your Mac: Occasionally, a simple restart can resolve various software issues. Make sure to save your work and then restart the device.

5. Check for Updates: Ensure your macOS is up-to-date by clicking the Apple menu and selecting "About This Mac" > "Software Update" to see if there are any updates available.

If you've tried these steps and the sound issues persist, it might be worth checking your hardware. Try using a different set of speakers or headphones to determine if there is a problem with the output hardware.

Let me know how it goes or if you need further assistance with any of these steps!
