I got Windows 7 for free from my university and I haven't encountered any problems at all except this one. I tried to turn on Audition and record some samples from a movie running in the media player but it won't record anything at all. Back in XP I could chose the input for the recording mic so that it would record any sounds being produced from inside my computer but I can't find that option now. My Windows 7 control panel looks like this:

That's just the Line-In and the peripheral mic that I don't use, no sign of the wav recording option.

Anybody have a clue?
