    You might still like to check it out:

    This SMC Firmware update adjusts the fan behavior in MacBook Pro systems (15-inch and 17-inch) when running under high workload conditions.

    Hi,

    I've installed drivers for the co-processor, thx for the help, but it seems like the sound problem persists...

    Regarding the driver, it's for OS X I think, since the file ends in .dmg.

    One problem solved, still the sound issue to go... :(

    I still think the AC 97 drivers might work, since under the specs it said "Mode: AC 97".

    There are so many different versions of the AC 97 drivers.

    Could you give me a more detailed description?

    I meant the driver for Vista 64-bit, the one that could pass Windows digital signature test.

    I think they are not gonna be approved by windows and therefore cant be installed =/

    I guess I have to wait to see if the windows crew will do anything about it to the real release...

    You have to uninstall the previous drivers by going to Control panel > Device Manager,

    Reboot and try the install again.
