Hello, A week ago my internal speakers disappeared from audio outputs on my 1G MBA (1.6/80gb). they would come back with a restart for a while, but now there just gone. I think I have tried every fix I could find: -I do not use headphones, so the toothpick is N/A. There is NO audio output -Re-installed OS-X -PMC Reset (speakers came back after the first time, but then disappeared) -PRAM Reset -Extended Hardware diagnosis: No errors found Another thing that is happening is that when the speakers are "missing", quicktime video is choppy, as is streamed video (like youtube). I also tried the garage band analysis and got the "Core Audio Selected Driver not found. (-10202)" message. Other then these things, the computer is functioning flawlessly... My Applecare warranty is up, and I am afraid of the impending doom in charges. Does anyone have any ideas of additional steps I can take?
