I got a problem with my microphone, when I connect my headset just 3.5 mm jack for sound I don't get any kind of problems, and everything is good, but when I connect 3.5 mm jack for microphone I get this really annoying sound, like screeching. I can't hear it because I can't hear my own microphone, but people on skype call, or teamspeak or steam call can hear it and they say it's annoying to listen to. Just so you know my microphone is connect to the back of the motherboard and I have already installed newest sound drivers for my motherboard, and also when I connect microphone to the front of the case screeching is even worse. Oh I almost forgot, I tried different headsets and problem is still the same. I tried listening to myself, like turned on the setting for "listen to this device" in sound options and it's really awful. It becomes more annoying while I'm playing games. Can you recommend some solutions that I can try so people won't hate me no more because of it. Here is a sample of 2 minutes of that sound just so you can hear it: http://goo.gl/nju8Ln
