help me :((((((9

Hello ....

ive got sb x-fi soundcard ,i connected mic and headset but i can hear myself in them
when i speak very loud (for example my fire alarm almost killed my ears) but can't when
mic is a bit away from my mouth.Other ppl can hear me on skype etc.

Seems like its only activated on certian level of voice but its so annoying.how can i turn it off ?

thank for anyone .

ps tried all options/default settings
