SE poor muffled sound quality 9.3.1
New iPhone SE has terrible sound with choppy, distant quality. Low volume.
system sounds that aren't working include camera shutter(no sound) FaceTime ringer.
I went to Genius Bar and they told me it was environmental and not hardware issue.
Tried hart reset, restore, switched notice cancellation, changed from LTE to data.
