Feedback from computer?

[CJL 10+ year member]

When i have my compy connected to my receiver, there seems to be feedback or something. If i leave no music playing, and turn up the receiver there is a low buzzing/humm noise. This has happened with all of my computers, and I wonder if there is any way to fix it?
it also happens with my digital cable box...//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

But if i unplug the Rca's connecting the components to the receiver, it quits.

sand your grounds to bare metal,most likely it a bad ground.

The problem is if your ground to the surge protector is corrupt or not. If it is compromised then you need to get a surge protector with isolation on ground. Higher end ones will have this. However, if the problem is developed from an idem that is plugged into your surge protector then you need to isolate that out.

May look into that direct box...the sub still hums even with the ground lifted.

What we originally used DI's for was for Keyboards and Bass's that had 1/4 outs to go to the XLR. But, I have found they have a million different uses....

Maybe I missed it, but are you using onboard audio? The inside of a computer is a very noisy place.
