    The title says it all. I am using the latest driver from Realtek. The optical beam will not turn off, and I believe this is the problem. The computer is looking for an optical device where there isn't one. How can I turn this off? I've played with the sound settings with no luck. This worked before I reinstalled Windows, I don't want to play games (And listen to music, haha!) without sound. If you have any experience with this, I would appreciate your help.

    Virtually the same issue for me. I just installed the 64-Bit Windows 7 on my Late 08 Alu. Macbook, and I can't install the SigmaTel audio drivers from my Snow Leopard disk. Got no sound and the headphone jack has a little red light.

    I had these problems when I installed the W7 RC, but I guess I downloaded the correct drivers for it to work.

    the drivers are out that fix the audio problems with the 64 bit windows 7 on a macbook pro (aluminum 13 inch).

    They fix the volume issue and also enable the ability to use the microphone as well.

    If you do some macrumors forum and google searches, you'll find them.

    If I remember correctly, I found them after finding a big thread on the forum and towards the more recent posts someone posted the correct solution.

    I'm pretty sure those "" drivers only work for xp/vista/win7 32bit. They won't work for people who have 64bit versions of win 7.

    I have 64 bit windows 7 and it did the job and it even says on the page that it can work for 64 bit windows 7.

    I posted the wrong one.

    Download, extract to desktop, and upgrade the drivers. It'll work.
