I have a soundblaster X-fi, and when I connect it to my monitor speakers through the RCA (actually TRS, tip ring sleeve) connectors, I get this high pitched whine at all times. I have to either turn off the speakers, or put some music on to drown it out.
If I disconnect the speakers from this PC and only keep it connected through the balanced 1/4" cables that go to another PC, it goes away.
If turn off this PC, it goes away too.
Any way to get this to stop? The sound card is "gold plated" etc, don't think it matters.
Maybe a new cable would help? I bought the cable new from a music store.. shrug
Ideas? The pitch is close to inaudible, but it drives me fuckin nuts.
Oh also I have a quality Seasonic power supply in my PC
