Hi there! I see you're experiencing an issue where the Crossword Jam app plays silently during gameplay but the ads have sound. Let's work together to figure this out.

To start, can you confirm a couple of things for me?
1. Have you checked if the in-game sound is enabled in the Crossword Jam app’s settings? Sometimes there is a separate toggle for music and sound effects.
2. Is your device’s media volume turned up when you are playing the game? Sometimes notifications or ad sounds use different audio channels than game sounds.

Once I know this, I can guide you better. Meanwhile, here are easy steps you can try:

1. Close the Crossword Jam app completely from your recent apps and reopen it to refresh the audio settings.
2. Restart your phone to clear any temporary glitches.
3. Make sure “Do Not Disturb” mode is off, as it can mute app sounds.
4. Check the app permissions: Go to Settings > Apps > Crossword Jam > Permissions and ensure it has permission to use your device’s audio hardware.

If none of that restores sound in gameplay, we can also try clearing the app cache:

- Go to Settings > Apps > Crossword Jam > Storage > Clear Cache.
- Then reopen the app and test sound again.

Please try these and let me know what you find out. If the problem persists, I’m here to help dig deeper or escalate if needed!

Are you satisfied with this starting point?
