    Hey everybody.
    I have a little bit of a problem with my MBP.
    Sound works when i hit F11 and F12, I can hear the sound ticks when the HUD comes up.
    Also, everything from iTunes works fine.
    I have a 150GB music library, and every song plays just fine.
    However, when I try to play audio out of any other program -
    Quicktime, Safari, Chrome, Firefox, Garageband, VLC, mplayerX... i get no sound at all.
    Youtube videos will play, but without any audio whatsoever.
    Quicktime doesn't seem to like this at all and crashes routinley.
    Does anybody have a fix for my problem?
    My specs are: 13" MPB, 2.3GHz i5, 4GB RAM, Lion 10.7.1
    thank you very much!

    Check Audio Midi Setup (in Utilities) and try setting the built-in Output to 44.100kHz, 2-ch-16bit integer.
