i had my headset plugged in at front panel and speakers at rear (but not switched on) i disconnected my head set and switched on my speakers, and they were all crackly distorted and such, i plugged headset back in (left speakers switched on) and the bad noise went. today i tried and speakers still terrible background noise, so connected headset and noise still there but not as bad. so disconnected speakers altogether and connected headset and still noise in background but faint. also i do an online radio hosting(poker) and other host's could hear the noise in background. so is my soundcard shot or my speakers? i am running windows 7 all drivers are up to date and did problem check and nothing.
