All of a sudden today when I got phone calls, I couldn't hear the person on the other end, but they could hear me. When I went to the sound settings, it showed that there was a wired audio device plugged in even though there wasn't. I haven't used headphones in about a month. Obviously music won't play out of the phone speaker either. I tried plugging in headphones and I could hear the music, but if I unplug them the music doesn't pause like usual, it keeps playing because it thinks they're still plugged in.
