tried that before .i have since gave up and am using my onboard sound now . as gtr2 is my main game.
i uninstalled the creative Sound Blaster X-Fi extreme music card and installed onboard realtek drivers .fortunately my m.board has full hd audio so is quite good .
i read through the creative forums and other online forums and found there are hundreds and hundreds of people having problems with creative xi-fi xp drivers.but as i said it works perfectly on vista.
see following link - http://forums.creative.com/creativel...hread.id=71962
bit fed up with messing around really . been here ages re-installing all my stuff . lol.
i tried different drivers and even their latest beta drivers but still had crackling sound after reading the above link and seeing how many people have problems like me i wont be buying from creative again thats for sure .
i will be fine with onboard sound .
thanks again for trying to help .
