I use Live but I used to have Enhancer. I forgot… in Enhancer you have to use the soundcard as well. So it should go like this:
1: Winamp/SQR ➡ Breakaway Pipeline ➡ Soundcard (what U hear) ➡ Edcast (using soundcard as input) ➡ Shoutcast DNAS.
In Live, you can entirely eliminate the soundcard. It leads to a much cleaner sound path as it is all internal and doesn’t need to be chewed up by a soundcard’s audio circuitry. Sorry for the mistake, I switched away from Enhancer a while ago.
Good luck!
