The problem triggered when i played the Mafia 2 demo a while back. During the beginning sound coming from the radio was distorted, synthesized, & crackling. Thinking it was an issues with the game, i didn't pay attention. After the game closed, the problems persisted when ever i multitask such as Playing a game and web browser, or web browsing and watching a video. I made windows search for the drive. No luck I went to the CD and tried the vista 32 & 64 and xp drivers. No luck Googling around, tried looking for the driver and it doesn't exist from this point. I tried one particular driver Cirrus Logic HD that seems to tone down on the crackling, but not getting rid of it completely. Any suggests or should a reformat help?
