My Ipad Pro keeps making typing noises inconsistently when typing

There is no ringer on the ipad pro. Just a volume button. Even when my ipad pro has no volume, whenever I type, it makes the typing noise but it’s inconsistent and sounds like it’s buggy/broken. This is my second ipad pro of the same latest model. My last ipad broke completely(bent in half somehow) and the screen went black..I could only see the screen very dimly if I were to shine my flashlight over it. Now with my second ipad i am having issues..is the ipad just built and designed poorly or is it just the software update? I have lost over a thousand dollars on my first purchase. And now i have apple care, paying every month in case my second ipad goes wrong and now Im starting to get concerned. This happens inconsistently and even the volume is inconsistent. If I were to show it to apple customer support I would probably need proof and record it and try get ANOTHER ipad and pay insurance on that one as well. If someone has answers please let me know.
