hey, im having some trouble. i installed studio one, drivers, etc onto my computer, plugged my monitors into my firestudio project, restarted my comp, plugged the firestudio in, and im not getting any sound. im trying to hear itunes or youtube and nothing. i have gone into sound preferences to make sure the firestudio was the selected source. i do hear hum when i put my ear up against the monitor (not a ton, just enough to make sure it works). what am i doing wrong?
