I have a Macbook Pro from 06 of december and i use it for leisure and recording music. I recently plugged in headphones to my mac and everything went haywire. The internal speakers didnt work unless i plugged in the headphones. Ive taken it to the mac store and the guy suggested that the sound card has been damaged or i might need a new output. i would like a second opinion. i know the speakers work its just when i plug in the headphones the speakers work and if i unplug the headphones the internal speakers dont work. The internal speakers do not show up on the sound preferences . What do i do? I have read threads about moving a toothpick or etc in the speaker i/o and the red light shows up and goes away WHAT DO I DO! please respond soon because im running out of time!
