Hi there! I understand the NU app sound isn’t working on your iPad. Let’s try to figure this out together.

First, just to confirm a couple of things:
- Is the sound working on other apps or just the NU app?
- Have you checked if your iPad is on silent or mute mode? (The side switch or Control Center bell icon controls this.)
- Also, can you tell me what iPad model and iOS version you are using?

Meanwhile, here are some basic steps you can try:

1. Check Silent Mode:
Make sure the side silent switch on the iPad is not turned on. Also, swipe down from the top right to open Control Center and ensure the bell icon isn’t red or crossed out. If it is, tap it to unmute.

2. Volume Settings:
Increase the volume using the physical buttons or Control Center volume slider to make sure it’s not low or muted.

3. App Sound Settings:
Sometimes individual apps have their own volume or sound toggle. Open the NU app and see if there is any in-app sound control and make sure it is on.

4. Restart the iPad:
Hold down the power button and slide to power off. Then turn it back on. This often fixes temporary glitches.

5. Update the NU App and iOS:
Make sure your NU app and the iOS are updated to the latest versions, as updates often fix bugs.

6. Reinstall the NU App:
If the problem persists, try deleting the NU app and reinstalling it from the App Store.

If you’ve already tried any of these, please let me know which ones so I can help further.
Are you ready to try these steps now?
