Shoutbox

Alright... I was trying to record a voice clip the first time, and a dialog box popped up with some preferences which I ignored, just clicking Next. And now, when I try to do voice clips, it doesn't detect noise coming from the computer (as in music). How can I go back to these preferences and change them? It's not in the normal Tools > Options...

EDIT: Okay, it won't do normal sound either...
