Hi there! I understand that the audio in your NIV Bible App on your Motorola device running Android 15 has stopped working. Let's work together to get it back up and running.

To start, could you please let me know:
- Did the audio ever work on this device before, or is this a new issue?
- Are you hearing any sound from other apps or media on your device?
- Is the app showing any error messages when you try to play audio?
- Have you tried playing audio with different Bible versions within the app?

Meanwhile, here are some initial steps we can try to fix the audio issue:

1. Check device volume and mute settings:
- Make sure your phone's media volume is turned up and not muted.
- Sometimes there’s a separate volume control for media/audio.

2. Ensure the NIV version you selected supports audio:
- In the app, confirm that the NIV version you’re using has the audio “play” symbol beside it.

3. Restart the app:
- Completely close the NIV Bible App (remove it from recent apps) and reopen it.

4. Clear the app’s cache and data:
- Go to Settings > Apps > NIV Bible App.
- Tap on Storage, then Clear Cache.
- If that doesn't help, try Clear Data (Note: This may reset app settings).

5. Update the app:
- Check the Google Play Store to ensure the app is updated to the latest version.

6. Restart your device:
- A simple reboot can fix many temporary glitches.

Once you try these, let me know if the audio starts working or if you still face issues. From there, we can explore more advanced fixes, including reinstalling the app or checking network permissions, since sometimes audio streaming depends on connectivity.

Are you able to try these out now?
