I have installed bootcamp and everything seems fine, al the drivers installed with the driver cd ok. although the only problem ive had is with the sound. the driver that was on the driver cd was a reltek one which didnt seem to work. i have tried the sigmatel one too, to no avail. although seemed to work better then the reltek as the lil app in control panel let me turn off the digital/optical out (red light in port) ans it correctly detects if there are headphones/something plugged in. Anyone else haveing a problem with the c2d macbooks? or could tell me what driver they used? i putting it down to either dogie install of xp+drivers or bootcamp not been updated for c2d mb's.......will try compleate bootcamp/xp re-install but want to try alternatives first.
