Camera or microphone not working in a LUME Hub meeting? Here's how to fix it

In a LUME Hub meeting, your camera and microphone depend on your browser's permission. When something won't turn on, the join screen or the room shows a message that points to the cause. Here's what each one means, from most to least common. While you sort it out, you can join with Entrar para ouvir (Join to listen).

The meeting screens still show Portuguese messages when the app is set to English, so each one below comes with a translation.

Your camera or microphone won't turn on

1. The browser doesn't have permission. The screen shows Aguardando sua permissão de câmera e microfone… (Waiting for camera and mic permission) while the browser asks. If permission was denied before, you'll see Não foi possível acessar a câmera (Couldn't access the camera), or the microphone, with a hint to check the browser permission or choose another device. To fix it:

1. Click the padlock or settings icon next to the address in your browser bar.
2. Set Camera and Microphone to allow.
3. Go back to the screen and click Tentar novamente (Try again).

2. Another app is using the camera. Video call apps, other tabs with a meeting open and recording software can hold on to the camera. Close them and click Tentar novamente (Try again).

3. The wrong device is selected. On the join screen, or under Mais opções (More options) and Câmera e microfone (Camera and mic) inside the room, switch Câmera padrão (Default camera) or Microfone padrão (Default microphone) to the right device. On a phone, Trocar câmera (Switch camera) flips between the front and back cameras.

4. Your operating system blocks the browser. On Windows and Mac, the system privacy settings also have to allow your browser to use the camera and microphone.

5. Only one of the two works. Câmera indisponível (Camera unavailable) or Microfone indisponível (Microphone unavailable) means you can still join with the one that works.

6. The address isn't secure. Abra a reunião em HTTPS (Open the meeting over HTTPS) shows up when the link was opened without https. Open the original link from the invite.

Problems during the meeting

• A câmera foi desconectada. / O microfone foi desconectado. (Camera or mic disconnected): the device dropped out, like a headset with a dead battery or an unplugged webcam. Reconnect it and turn it on from the meeting bar.
• Microfone silenciado pelo anfitrião (Muted by the host): the host turned off your mic. Only they can release it.
• Reconectando... (Reconnecting) or A conexão foi interrompida. (Connection lost): your internet dropped. Click Reconectar à reunião (Reconnect to meeting) or use Reconectar (Reconnect) under Mais opções (More options).
• Compartilhamento de tela indisponível neste navegador. (Screen sharing isn't available in this browser): common on phones. Use a computer.
• Fundo virtual errors (virtual background): the blur or background didn't run on your device; your camera keeps working without the effect.
