Here is the truth. The microphone is a pinhole on the bottom of the camera. It picks up the vibration of the desk more clearly than your voice. If you are typing, the other person hears a thunderstorm.
Unlike high-end cameras, your HDliveCam does not have a sensor to detect the lens cap. The manual calls it "the cover for privacy." What it doesn't tell you: If you leave this cap on while plugging the camera in, the auto-exposure algorithm will "learn" darkness as the baseline. You will spend 20 minutes troubleshooting a black screen before realizing the cap is on. hdlivecam manual

Do not search for "HDliveCam driver." You will land on a page that asks for your credit card. Instead, look at the USB plug. There is often a tiny string of text: HD1080P_V2.3 .
