I bought a new Logictech headset with mic. I have been told that my VOIP has an anoying buzz in the background. I did a mic test and sure enough "Buzz". I have adjusted and tested every setting in the Audio section with no luck. I only have this buzz when playing DDO. All other games are fine. The sound settings in windows (XP) have little to no adjusting. Is there any way to get better sound controling software to help remove the buzz?
