    I have a straight connection from the sound card (green headphone jack) on my computer 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?

    Hi mate!

    Can you try switching from the phono inputs to tape/auxilary or whatever is similar? Usually buzzing indicates cable/contact problems but you never know...What happens if you plug standard PC speakers/headphones directly to your sound card output? Does the noise still exist ?

    EDIT:Also check with a stereo configuration instead of 5:1. The green sound card output is stereo only so the noise could be related...

    There is no noise when using the PC speakers.

    You have a "hum loop" caused by the amplifier chassis being designed to "float" isolated from ground, while the PC is grounded.
