recording from any source not working

related to "Static/crackling during Recording all of a sudden" post

I'm using windows xp sp3 (tested on windows xp sp2 too)
it happened to me these days when I tried a skype call, no one could hear me. So I checked the microphone monitoring and I could hear only static, tried in linux too only the output is ok.

If a different mic doesn't work and you're within a year of purchase, I'd recommend contacting us about a replacement unit.
