I purchased a the new 12.9" Pro a little over a week ago. When using FaceTime/FaceTime Audio/phone calls through iPad, I'm getting audio playing out of multiple combinations of the 4 speakers. I would expect that it would play on all 4. Instead, I randomly get audio out the 2 speakers on the home screen button side, the 2 speakers on the long side facing up in landscape, and finally it also randomly plays on all 4 speakers. Several contacts with Apple Support have provided contradictory information on how it's actually supposed to behave: "You should have sound coming from all 4 speakers; Apple optimizes its programs to take advantage of the Pros' features" (this makes the most sense) and "based on the fact that my iPad does this, FaceTime is designed to only work out of 2 speakers". Since I'm getting contradictory information from Apple Support, I'm considering returning the unit for a refund until this gets sorted out. Has anyone else run into this issue with their ipad Pro?
