Sounds like for some reason it's trying to change to digital output mode. Next time it happens, look at the headphone jack. If you see a red light, it's in digital output mode. This happens from time to time, and you basically just try and put in a pair of headphones or speakers a couple of times until it turns off. If you can't get it to switch back after a dozen or so tries, you should probably take it to an AASP or Apple store, because you're going to need a new logic board.
