I can hear my microphone picking up sound through my headphones, however when I try recording vocals the track is left empty. I have already made sure that the "record enabled" button is on and that the 48 V is passing through my Audio Box, I can even hear my instrumental in my headphones when I try to record the vocals. I've even made sure to plug the Audio Box into the same USB port which was used to install my driver. Nothing seems to work, at this point I'm thinking i must be configuring the Audio I/O incorrectly.
