Speakers in Apple IPad Air 5

Don’t be fooled by the number of visible grilles…

The iPad Air5 has only two built-in speakers. With your iPad positioned in Landscape screen-orientation, there is one speaker on the left and right side of the iPad - providing a stereo pair.

To reiterate, your iPad Air has only two speakers. While you may hear sound from the other speaker grilles, only two have an actual speaker.

If you have any concerns, you would be best advised to visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad:

hi there, please try this steps in order to repair the sound coming from your iPad. Start With restarting the iPad, if this is not working, follow these steps

If you prefer, here are some more steps you can try on your own. After following these steps, you might still need to contact Apple Support to discuss service options.

1. Remove all screen protectors, films, or cases from your device. 
2. Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver isn't blocked or dirty. 
3. If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry.
4. Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times. If you don't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker might need service.
5. If you hear sound, try making a call with your iPhone and turn on speakerphone. On iPad or iPod touch, make a FaceTime call. If you still can't hear, or hear static or crackling, then your network or reception could be the issue. Try to call again later, or from a different location.

You are very welcome.

Hopefully your concerns have been laid to rest - and the perceived problem resolved.
