When I start recording I can hear the background sounds. Example: Me talking on vent and other crap. And when I unplug my microphone it does not record any sound at all. This is the first time I ever had this problem cause when I used FRAPS before it always recorded the in game audio.
weird... must be a setting somewhere that you have it recording mic/line-in instead of the sound buffer. No idea.
One thing you could try is going to the sound properties (double kick the speaker in the system tray), change over to recording options (file, properties, recording I believe), and then un-check the microphone/line-in option. That way it can't record from that port.
