I noticed that I can hear myself (faintly) but very loud when I blow in the mic, in my speakers. I've tried adjusting the recording levels in Control Panel/Sound/Recording/Levels as well as the Microphone Boost (which feeds back when its turned up), and it doesn't make any difference. I cannot understand why I am hearing anything in the speakers if the level is set to 0. The mic (which seems to work fine) is a cheap clip-on style plugged into the mic input of an older Asus motherboard.
