While creating some video lectures with Captivate 9 the audio recording stopped working. It worked perfectly for one slide, but the next it was extremely muted. I've tried several different microphones, without any success. When I re-calibrating with the auto calibrate function it seems like Captivate barely registers the audio input. The "Checking Input Level" bar doesn't register audio unless i literally yell, but then states the "Input Levels Ok". Any advice or trouble shooting?
