Windows 7: Hissing in Realtek ALC662 Audio

14 Aug 2012   #1

Windows 7 Home Premium 64 bit
Hissing in Realtek ALC662 Audio

Hi, Everyone

I just got a new computer and it has a realtek alc662 audio card on the motherboard built in. When I use the computer you can hear an audible hiss from the headphones and speakers when you move the mouse or when the hard drive spins up. I believe its some kind of interference but I can't figure out this problem.

Here are my specs
