I just got one of these cards and I'm having a problem. I've got a set of speakers connected to this thing (Klipsch), and I'm getting really bad noise every so often. So far I've only heard it happen when I'm using iTunes. I don't know how to describe it, other than to say that it's a loud, static-like noise. It goes away if I pause the music then hit "play" again. It happens every time I use it, at random intervals. Anyone else have this problem or have any suggestions as to how I can go about fixing this?
