If Zoom is not picking up your microphone, you can select another microphone from the menu or adjust the input level. Check Automatically adjust microphone settings if you want Zoom to adjust the input volume automatically.

Why does Zoom suddenly have no sound?

On Android, you can go to the Zoom app's settings and turn on Auto-Connect to Audio. If you're still having trouble, a pair of headphones may be the fix you need.

Why is my audio not working?

You might have the sound muted or turned down low in the app. Check the media volume. If you still don't hear anything, verify that the media volume isn't turned down or off: Navigate to Settings.
