Graphics card causing interference in Headphones On my computer, when I plug my headphones into my rear headphone port I get great sound quality but when using the more accessible front panel headphone port I get a lot of interference.

"You can buy some braided copper shielding at most electronics supply places (or, failing that, you can try some aluminum foil, although it won't be nice looking or possibly not as effective).

You're going to want to ground the shielding, as well as keep it safe from shorting the motherboard. I'd use a piece of shielding long enough to shield the cable, then secure the tail under a screw or other available place in the case. You may also want to use insulation of some kind (tape, etc) anyplace that the shielding might get close to the motherboard or similar areas.

It's also possible that the interference may be coming over the power system."
