One thing to look out is what is the microphone that Zoom is actually listening too. I used to have a USB microphone with a mute button that was very convinient. Litle did I know that Zoom was set to the laptop's integrated microphone... Sometimes you can have even more microphones. External webcams may have a microphone and some monitors as well (when used as USB hubs).
