audio on my MacBook stoped working

The audio on my macbook suddenly stopped working. When I click on the audio adjuster, it won't even let me change the level (the little circle is white now, not blue).

But when I plug in headphones or an external speaker, everything works fine. I can once again adjust the audio and get sound

There was a red light eminating from the audio out jack for a while

The red light means your digital audio out has switched on. You can insert a plastic toothpick in the hole and try and switch it off. The switch should be at the 3 o'clock position and go towards the 6 o'clock position. Some people also have had luck inserting their headphone jack and pulling out a few times. Another recent report was that inserting the headphone jack and turning it in the hole helped.
