Headphone noise

when i plug my headphones into my jack (i have a logitech x530) i have some noise, sort of a crackling sound that really distracts from the experience.

when playing music its ok, but in quiet scenes in movies its really annoying.
for your information my headphones are a Koss. (btw i checked the Koss is OK, plugged it into my Ipod)

is there any way around this?

Open the mixer (run: sndvol32), go Options+Properties, check all boxes, and then disable and slide to the minimum everything you don't use, especially CDAudio and PC Speaker. You probably only need the global one (leftmost) and Wave.

Also open the sound control panel applet (run: mmsys.cpl), go to the Audio tab, click all the advanced buttons and in the windows they pop up, navigate the tabs if any to find quality sliders, which you should set all the way to the right if they aren't.
