All was fine on my Mid2010 MBP 15" till I plug a pair of earbuds in to listen to a movie. After unplugging them, no audio detected. Never had this problem before I installed Mavericks. Audio still works when earbuds are plugged but the audio is not detected when unplugged. Can't even change the volume level. I also get a red light coming out of the headphone jack. Anybody hear of this problem?
