hey, i just bought some new klipsch 2.1 promedia speakers. I was so excited but when i started playing music, the crackle, (which i thought the new speakers would fix) was still there. The crackle isnt steady, it is sporatic. i do have the volume in the volume control very low on my pc, but the crackle is still there. I have plugged the speakers into my ipod, and the crackle was gone, so i know the problem is somthing with my pc. i sprayed the green input where you plug the speakers into with compressed air, and the crackle is still there. Maybe it is something to do with my sound card? I still have the same sound card that came with my emachine T6412. Please help, i would really love to hear clean sound out of my brand new speakers.
