I just installed the Hercules GT in my computer. It works fine in win me and win 2000 but doesn't seem to work in win XP. Tried the default win XP drivers but the sound quality was terrible. Upgraded to the win 2000 Hercules drivers and I now get a high pitched screeching sound when I play any type of sound. Tried the drivers on the CD and version 2.01 on the Hercules website, nothing seems to work. Has anyone come across this problem and have a solution? Any help would be appreciated. Thank you
