So I DJ with Winamp. I didn't even consider it, when I tested the stream a while ago, but I have NO clue where the mic input is. The only thing I can remotely find is "Audio Capture", but that's for recording URLs, right? Either way, I have no idea how to set it up.
At the time of writing this I have a gig in like 2 hours, and if I can't get it to work, I have to hop over to Old winamp and hope it doesn't crash on me.
Originally, the mic settings were on the Shoutcast plugin window, but it's no where to be seen, now.
