Joining an important District meeting only to find out nobody can see your video or hear you speak is incredibly frustrating. This usually happens for one of two simple reasons: your internet browser is blocking access to your hardware, or Google Meet is looking at the wrong microphone or camera.

If Chrome does not have permission to use your camera or microphone, Google Meet will remain completely dark and muted.
Look at the very top of your Chrome window, inside the address bar (where you type website names), all the way to the right side.
Look for a small video camera icon with a red "X" or a slash through it. This indicates that the browser has blocked your devices.
Click that small camera icon.
Click Done, then refresh your browser page to reload the meeting with your hardware active.
If your browser permissions are open but you are still a ghost in the meeting, Google Meet might be trying to use an old plugged-in device, a closed laptop mic, or a disconnected headset.
Look at the bottom menu bar inside your active Google Meet window.
Click the More Options button (the three vertical dots).
Select Settings (represented by a gear icon).
In the menu that pops up:
Click Audio: Under "Microphone," open the dropdown menu and select the specific headset, external mic, or built-in system mic you are currently trying to use. Speak out loud; you should see the small blue dot indicator bounce if it detects your voice.
Click Video: Open the dropdown menu under "Camera" and ensure your active webcam is highlighted. If successful, you will instantly see your own video preview appear in the small box.
Quick Tip for Volunteers: If you are using an external headset or web camera that plugs in via USB, physically unplug it from your computer, wait 3 seconds, and plug it back in. This often forces the computer and Google Meet to re-detect the hardware automatically.
