    Greetings!

    I was using my Macbook 3,1 running OSX Snow Leopard watching youtube when i plugged my apple head phones in. After about half hour of use i unplugged my head phones and the Volume greys out. I cant have anything playing from the internal speakers. But as soon as i plug something back into the jack the headphones work. odly enough i looked into the head phone jack and there was a red light flashing. Its gone now. but it flashed and stayed on now it disappeared.

    It just started working as i plugged in and unplugged my other headphones without a mic. BUt as soon as i plugged in my apple head phones with the mic the red light inside the plug flashed and apon unpluging the headphones the icon volume is greyed out again!? Whats going on?

    Macbook 3,1
    2.2ghz Intel Core 2 duo

    Sounds like it's triggering the optical audio out (the red light). Sometimes the little switch gets bumped and stuck.

    Some have success using a toothpick to reset the switch at the end of the jack.
    Others used a little software trick as referenced here

    I'd give the software fix a try before sticking objects into the jack, but I did have my late '08 model get stuck once and I managed to move the switch back and it's been fine for the last 6 years.
