I have only had my iPad Pro for approximately two months. Previously had an iPad mini. About a week ago when I pushed my enter button on a text message, a horrible loud screeching noise started that I could only stop by turning it off. Tried to send message again and it did it again so I turned it all the way off, let it sit and turned it back on. The sound did not come back until just now when I pushed my speaker icon to do a voice to text on a message. Truly a horrific sound that sent my animals fleeing from the room. LOL Any ideas?? Come to think of it, I "might" have been using the same program both times. That program being messenger that is attached to the Facebook app. Could that be it?
