    Hi new to Mac already encountered a problem.

    The problem is my speakers don't work. They make a crackling noise. When i turn up the sound using the F11 and F12 key each time i turn it up or down it crackles. I tryed to play video of multiple programs. Youtube, iTunes, VLC.

    MacBook Pro 15Inch (new model)
    2.8GHz Processor
    320GB 7200rpm

    Downloaded applications so far:
    Handbrake
    VCL
    Ventrilo
    Blender 3D program
    LimeWire
    iAntiVirus
    SMC fan control

    I'm currently running TechTool Deluxe to see if it catches anything. I also play World of Warcraft and i run my fans at 6200RPM to keep my laptop cool while i play. The temp usually sits around 72-75 on average for 4-5 hours. I hardly play sound on my laptop speakers I usually plug in earphones or play on my 2.1 stereo speakers. I have an apple care package plan so I may just take it to apple tommorow.

    Any suggestions?

    In the Sound preference pane, what device is selected for output?

    But the line out for your headphones and external speakers works fine, yes?

    You're right, the crackling could well be a hardware issue with the laptop's built-in speakers.
