    Sooo the microphone in my new macbook keeps dropping out...
    like on video chat I'll be talking and then my microphone will stop recording audio randomly for 2 seconds then it'll come back 2 seconds later....
    also I noticed if I yell into the microphone (don't ask) the microphone input level will automatically lower itself, but then it won't go back to the input level it was at before...
    sooooo yeah :(

    Perform SMC and PRAM resets and see if that helps. If not you might have to call into AppleCare. If I remember correctly, there is a .plist file or just a file that can deleted.

    You also might want to create a new user just to see if it's just the user or system-wide.

    EDIT: go to "Macintosh HD/Library/Preferences/" find and delete "com.apple.audio.DeviceSettings.plist. Restart your computer and see if that helps.

    Chances are it's a hardware defect. I'd set up an appointment to the Genius Bar or call AppleCare to set up a mail-in-repair
