How do I get my sound working again? It works with Headphones, but when I unplug the headphones a red light is coming out of the headphone jack and I can't adjust the volume on my Macbook Pro.
macRumors ref: No sound out of MacBook speakers & red LED in Headphone jack.
And, for the brave hearted,
Closing the lid and reopening it resolves this for me whenever it occurs, this isn't optimal, but it's quick and easy. When this happened to my macbook 13" unibody (aluminum) model it was very frustrating as I would plug in headphones and they'd seem broken.
The same thing works if your tap-to-click feature stops working, or in that case you can use the system prefs to disable and reenable it.
