I'm using RealTek HD Audio sound card on my Asus Z77 V-Pro, the first time i used a headset it went fine, then it bugged and this started happening i bought a new one but still it's not working, i use sennheiser 320 and it's really new so it shouldn't have this problem, i tried reinstalling drivers with no success it's really weird, i have to raise increased mic to +30 before it's actually heard, but i do know the mic works but in a really weird way, i tried "configuring the mic" but it's not available on my language, it doesn't say model either on "recording" section it only says RealTek HD Audio
