If your sound cannot be heard by the other side, make sure that:
- You are using headphones with an integrated microphone and they are properly plugged in.
- You are using Chrome as it offers the best performance for the lesson space or Safari if you are on macOS 10.11 or later.
- Restart your computer.
- If you are on a Windows computer, make sure to check your microphone levels and that it is not being muted. See how to do this in the video below.
