Bloody Macbook Pro is at it again. There is this little red light that likes to pop up on me inside the audio-out port of the Macbook Pro. I've heard that its the optical out detecting an optical connection. The only problem is that I don't have anything plugged into it. This also causes my computer to stop playing sound or flicker the sound output as the red light flickers. Here's a video of my woes.http://www.youtube.com/watch?v=YYshCDVXBfc So, what should I do? If it doesn't do this when I visit Applecare, will they take the video as proof enough?
