When you select the microphone you want to use in the session, the microphone level bar is displayed, and as you speak, it will move accordingly. This indicates that your microphone is working. By clicking “Next”, you can go to the next page.
If there is no microphone listed here, you need to make sure that there is a microphone connected to your device.
► Sufficient bandwidth is one of the most important requirements of a live session.
► If you live stream with your webcam, you need a minimum upload bandwidth of 250 Kb/s.
