Hello. Recently I've bought the Roccat Kave gaming headset and to enjoy it ( i would not say to the fullest but at least the bass ) I bought along a Creative SB X-fi Titanium PCI-e sound card. It was all fine untill a couple days ago, where I started to feel distortion and crackling sounds when listening to anything on the computer. It is not from the headset because it works just fine when connected to the audio tray on the motherboard. Here's my current specs : ECS GF8100vm-m5 XFX ati hd 6870 xfx 450w pro amd athlon x2 5200+ I would really appreciate any tips on how to fix it because it is quite annoying .
