Hey guys ive been having some weird mic feedback or something. when i talk into the mic on my headset i can hear myself speak and breathe and stuff. Its a logitec 5.1 system (cant remember the model) and it has a separate spot for headset connection attached to volume control. The problem is still there when i plug directly into the sound card. Is it my headset? My sound card? or what? Should i adjust some setting or something? Any input or help would be greatly appreciated
