Imported movie--no sound
I have a MacBook Pro Retina (mid-2015) running High Sierra 10.13.4. I have imported video from a Canon Optura Xi (mini DV) digital camcorder into iMovie 10.1.9. (I have done this in years past with no problems.) The video imports with no problem; however, there's no audio. I have checked all the connections, and restarted both the camera and the computer.
Suggestions?
Note: a previous similar thread suggested importing it into QuickTime then iMovie, but I can't get QuickTime to recognize the device for import. When I checked the Mac's System Report, the device doesn't show up under Hardware, but under Thunderbolt, it does say "device connected."
MacBook Pro, Mac OS X (10.5.8)
