iOS 10 stopped it cold

Updated to iOS 10 and now it functions perfectly fine except the alarm doesnt go off. It says it did, but no sound or anything. Tried all different settings, reinstall, and nothing. Have to try a different app if I cant get this fixed today........ I was late for work this morning. Oh and my wife has the exact same problem so its not phone specific.
