It looks to me like your recorded amplitude is WAY too small!
Try recording and playing back sinewaves, and make the recorded sine louder and louder until it starts to clip obviously when seen on the 'scope.
Or if you don't have a sine generater then record other constant freq sounds like speech and find the amplitude where it starts to clip. You need a recorded amplitude just below that.
