Default Buzzing noise on speakers

I have a straight connection from the sound card (green headphone jack) to the phono (red & white) input on an amplifier. The cable is stereo to phono (1.5m long). When I have the volume low on the pc and turn up the volume on the amp I get a really bad buzzing sound on my speakers, espically the center speaker (I've a 5.1 setup). When I play music on the pc this noise is very bad. I get this noise both from the onboard and PCI sound cards. This is no conflict of sound cards on the pc as this occurred before I instlled the new sound card. I also tried a different stereo to phono cable but the noise is still there. Any suggestions on the cause of this noise or how to eliminate it?

Yeah turn the volume down on the amp a bit and turn it up on your PC a bit.
