If you have connected a webcam or external microphone to your laptop, you will likely need to select that new camera or microphone to use it in Zoom.
To follow these instructions, first launch Zoom and start a meeting. I recommend always having the camera or microphone connected before you launch the Zoom app.
Change Your Camera in Zoom
Look for the Start/Stop Video button in the bottom-left corner of your Zoom window. This is the button you use to turn your camera on and off during a meeting. In the corner of this button is a small up-arrow. Click this up-arrow to see a list of cameras available on your computer.
To change cameras, just click on the camera you want to use; your video in Zoom should switch to that camera immediately. Zoom will likely default to the built-in camera, so you may need to change cameras this way every time you launch Zoom.
Change Your Microphone or Speakers in Zoom
If your webcam has its own microphone, or if you have connected a separate bluetooth or wired microphone to your laptop, you can change your Zoom microphone and speakers in a similar way.
Look for the Mute/Unmute button in the bottom-left corner of your Zoom window. This is the button you use to turn your microphone on and off during a meeting. In the corner of this button is a small up-arrow. Click this up-arrow to see a list of microphones and speakers available on your computer.
The top section lists the available microphones; click the microphone you want to use and your audio input should switch to using that microphone. If your webcam has its own microphone, you should see it listed with the same webcam name you saw in the list of cameras above.
The middle section lists the speakers or audio output devices which are connected to your laptop. If you are using a bluetooth microphone/speaker device, you can select it here to use as a speaker. You audio output should immediately switch to playing through that speaker.
Zoom will likely default to the built-in microphone and speakers, so you may need to change these settings every time you launch Zoom.
