Hello. My motherboard is gigabyte GA-P31-DS3L. I have the plantronics gamecom 367 headset. First of all, I want to know a few things about microphone boost; what is, how it works and why do I need? Secondly, I want to ask you what are the recommended settings to use with this headset? And why do my friends on skype hear a noise when I use microphone boost(+20 dB) when I mute the microphone and turn it back on. Please note that that noise disappears as time passes. But the question is why do they hear a noise after I turn on the microphone when I use microphone boost? Thank you in advance. Good-bye and have a good time! P.S. Sorry for my bad english, I hope you will understand.
