First make sure that the input gain knob next to the mic/line inputs is turned up. Notice that there are actually two knobs there even though it looks like only one. The center knob is for the mic input and the outer ring is for the line input.
Second, make sure that the inputs are set to MIC-LINE as opposed to LEFT-RIGHT found by pressing the Effects button in the Vocal Genius section and looking in the upper right of the display.
Third, make sure that at least one (up to four) of the harmony parts is active by pressing the Edit button in the Vocal Genius section; active parts have a staff with notes and muted parts have a speaker with an X through it.
Fourth, you do have the Harmony button activated in the Vocal Genius section, don't you?
