I bought USB microphone,and look what's happening-i turn him,driver automaticly installed but when i try to speak nothign happening.In shortly it doesnt work.But when i press record in windows recorder it record what i say,but i can hear recorded waw only AFTER i turn off microphone.Could be this compability problem?I have integrated realteak chipset soundcard.I was thinking about buying usb sound card,but not so sure will that work.
