Ok first off I have had my build running for almost a year. Originally went with XP when I put it together. However as time went buy I bought a WD 1 TB Caviar Black and decided to put Vista Ultimate x64 on it for a test drive. I loved it so much I kept it. In XP the headphones were dead silent when the volume was on but no sound was coming out. However on Vista, there is constantly some feedback or noise(which ever you like to call it). It is similar to the sound of an old dial up modem.
I have am using the on board sound for the ASUS P5N-D, not a sound card. Running these speakers:

Any suggestions? Drivers should be up to date btw.
