Oh no I fix the problem, it was not my sound card (buildin Realtek AC'97). The problem was with the SATA driver that Vista installed. I have a SATA harddrive. Resolve the issue by updating the SATA from the XP partition.
Many people are having the same issue, seems like it when I was googling around. Just wondering if anyone on this forum has the problem, because it can be fix by reverting to the XP driver depending on what hardware is causing the sound to stutter.
