I have my Audiobox 96 plugged in and set up with my computer. When I go into Studio One (5), I can hear the sound coming through my mic that's plugged into the audiobox, but it won't record any sound and doesn't register it (the levels don't move at all). When I look at the track input, it says "Input L - Disabled 1". How do I fix this so I can record with my mic?
