No audio input for voiceover in iMovie 10.1.13 (Catalina 10.15)
I'm trying to record a voiceover for an iMovie in progress. Neither the built-in microphone nor an external one shows any input volume on the little meter to the left of the record button. Yet under System Preferences/Sound, it shows input volume from the microphone. So when I try to record, all I get is silence. My speaker volume is on (high), so it's not an output problem. Why isn't iMovie tapping into the sound that the microphone is registering?
