    Hi Guys,
    I have a 13'' mac book pro (running OS X Lion 10.7.5) . and the sound has gone comletly on it unless i have headphones plugged in. I have tried everything including re -setting the PRAM (which i have done). Please help me. :( As i am a student who needs her laptop for her studies and cant afford to send it away to be fixed :confused:

    "I have tried everything" puts it in the "time for the shop" category.
    System Preferences > Sound should have been #1 on the list

    Make sure you zap the PRAM three times in a row (three chimes). And it might sometimes take even more to get the sound to come back. :)

    You wouldn't happened to have spilled water now, would you? Happened to my last laptop. Spilled just a few accidental droplets, I'm talking less than a small sip-worth of water on my laptop while it was closed. Functioned fine but my speakers were RIP since that day.

    It's possible that...

    .... the prongs of the 1/8" headphone jack are stuck & disengaged, thus no sound from the computer's speakers. Sometimes a bit of light "wiggle" of the phone's plug will do the trick. I have even once used a safety pin with it's tip bent slightly to fix the problem you described.

    If it's under warranty, let the pro's look at it. My suggestion is a last ditch option as opposed to a possible expensive repair.
