Macbook audio does not work

[Crosswind 9]

I plugged in some old speakers into my macbook pro and unplugged them and a red light appeared and my internal speakers would not work. I have restarted my computer and i hear the booting up sound but the speakers dont work again. The red light isnt on now but the speakers arent working still.

Please, what do i do?!

I'm guessing the "red light" was your optical audio. Look in system preferences to make sure the built-in audio is selected as output.

If that doesn't fix it, check

actually i just read some other thread and it said to use a paper clip. You stretch it out and stick it in as far as it goes and slide it on through the left side. Worked like a charm. http://discussions.apple.com/thread....14884&tstart=0

Eric is correct there, the red light is the optical audio, but i've seen this before. The plug from your old speakers triggered the optical sensor. it stays on and the only thing you can use is headphones, i believe. It's stems from a problem on the board, but there are a few discussions and low tech solutions below.

Here is a link to their forum http://discussions.apple.com/thread....sageID=3255575.
I also got mine working with the toothpick. Inserted it gently a few time in the 6-7 o’clock position. There is a very small sensor or ?? in the back of the port. Once you touch it lightly, all is back to normal. I hope that works for you.

You can always take it to the apple store as well... and don't forget to upgrade the APPLE CARE to 3 years.
