So, I've looked around for a solution for my problem, but can't seem to find one. When I plug my speakers into the rear 3.5mm jack of my soundcard (Creative sound blaster z), I get a static-y noise, but when plugged into my front headphone jack, I don't. Also, I can't hear the static sounds through headphones plugged into the rear 3.5mm jack. Just to test the speakers further, I plugged them into my MacBook and they worked perfectly then as well. I've updated all of the sound drivers etc. but I can't seem to make them work when plugged into the back of the sound card. Any help? Thanks.
