    Is this only when you're outputting audio to an external device through the video-out port or a TOSLink connection to the headphone port, or do the controls not work even when audio is going through the built-in speakers?

    it seems this is happening when I have itunes on or even if I am on a website that has a video- I havent tried it with a cd yet but when I hit F10 it shows a shaded speaker with a line through it but also shows full volume in white bars and under that a circle with a line through it....... ?

    I havent tried any out put source- just the built in speakers I think

    So the built-in speakers are working — yes? — but the keys don't control the volume. Is this correct? Or are the built-in speakers not working at all? If they aren't, is there a red light on inside the headphone port?

    yes the built in speakers do work but the control keys dont control the volume
