I Have A iPad 7 Generation My Volume Down Button Is Not Working

First off I would see if you are still under Apple’s Warranty or have Apple Care at this website. If you aren’t under warranty and you don’t want to spend the money taking it somewhere you can fix the button for the volume down or replace the cable. Sometimes the little black part on the button falls off and doesn’t allow you to press the button anymore. I can’t tell what iPad you have so I have listed the parts and breakdowns for both the iPad 7th gen and the iPad Air 3rd gen. From my experience iPads are one of the hardest apple products to work on so good luck!
