Windows 10: Why isn't there any sound with playback of a video made with built in camera on my computer?

I've made short videos with my built in camera on my Lenovo laptop Windows 10, but there's no sound when I playback the video. Why is that?

Windows Camera app not recording sound

I have been trying to record video using the Windows Camera app (Windows version 1909), but no sound gets recorded. The default audio input device is the microphone in my webcam, and the audio preferences for Camera are set to default. I was able to use the same setup yesterday to have a Skype conversation with audio capture. I have tried replaying the video recorded in the Camera app in VLC, but there is no sound there either, so the problem is definitely with recording rather than playback. Why doesn't the Camera app record sound?
