No sound on my Quicktime movie
I've got a M1 Mac Mini running Sonoma 14.2.1. I've just made a video using my new Camera glasses. The recording is fine but there is no sound. I have three options for the sound. I can play it through my Mac mini, the speakers in my Philips monitor or Via a USB connecting external speakers. I've tried playing the video through both QuickTime Player and Apple TV. Both work for the video but not the sound. I've used settings to try out the volume at various levels but no joy.
Mac mini, macOS 14.2
