No metronome "beeps" in Pro 9

Since upgrading to Cubase Pro 9, I cannot get the metronome to make beep sounds any longer, either in record or play. It worked fine in Pro 8.5.2 but since installing Pro 9, it doesn’t work even though the settings are correct. Any help? Attached is a snippet of my Pro 9 metronome setup dialog box.
