After a sum total of 2-3 hours of trying out ways to make Youtube pick up audio, it turns out it did anyway, just the bar doesn't move before you're actually recording. Annoying waste of time but oh well.
My Youtube account is PaulyPlz - I planned to change the name before I uploaded but I really couldn't be arsed. I've put up a couple of videos so far, in case anyone want to check them out.
Hmm. I've changed my youtube name. And I've removed one of the videos which was just me dancing around playing out of time to Radiohead's "15 Step".
Blah.
