Is there a good way to broadcast two feeds from one pc? I was able to open two icecast windows on my desktop how ever the typical inputs (mic and line) would just bleed into eachother. Would purchasing a usb line in (mic) jack allow me to split the two "channels" so I can select my built in jack for one feed and select a usb jack for my second feed? Basically I want one dedicated scanner "scanner 1" linked through what we'll call "default jack" (buillt in line in or mic) to provide audio for "feed 1" and another dedicated scanner "scanner 2" for a second feed we'll call "feed 2" using the usb jack which I'll call "usb jack 1". Sorry for the specific labeling! I figured it may help break down the explanation process.
