Today I tried to have a FaceTime chat with somebody, and although I could hear them, they couldn't hear me. The microphone definitely works. I can record voice memos, videos, and make phone calls just fine. Also, in that limbo time after I place a call and initiate FaceTime, but before FaceTime connects, the person on the other end can hear me. But, after FaceTime connects they no longer hear me even though I hear them. It's been a few weeks since I last tried a FaceTime call, and it worked just fine then. Has anyone else experienced the same problem? Any ideas?
