This sounds like a problem I had quite some time ago. I was getting clicking when playing DVD or music video's, it sounded like static. It came down to a conflict between the video driver and the audio driver. The clicks arn't actualy clicks, they are very short gaps in the audio. The only way was to update the audio & video drivers. So if the drivers from F/S don't do the trick for you, then go to the manufacturers web sites, for more up to date drivers. Good Luck!
