In the mobile app

Choosing a camera or microphone
Before you go in, choose from the lists under the preview. They appear when you have more than one.
During a call, open Settings: Audio for the microphone, Video for the camera.
Connect headphones or a camera before you open the call. If you plug one in during a call, reload the page to see it in the lists.
Nobody can hear you, or you cannot hear them
Look at the microphone button: if it is red with a line through it, you are muted, and pressing it unmutes you.
Check that Settings → Audio uses the microphone you are speaking into.
Sound comes out of your device's default speaker or headphones, so check your device's sound settings and volume.
If there is still nothing, hang up and press Enter Call again.
