I have a Macbook Pro 15" , C2D 2.33ghz. I have the 7100 version of Windows 7 and everything worked perfectly except for the sound. No matter which bootcamp driver I try or even Realtek's own vista one nothing works. I downloaded the bootcamp 2.1 drivers and everything installed correctly , including the realtek ones. All the hardware looks fine in device manager but I dont hear anything out. Should the default be speakers? It seems that it keeps the driver as microsofts own and it doesnt say anything about realtek. Could that be the problem? I did not try the microphone jack yet but will in a few minutes. Even if there is a hack , Im willing to try it. What is the exact audio chipset on this model of macbook pro?
