Join the Audio

Listen Only allows users to quickly join the conference as a listener only (no microphone check). You will be able to change your audio preference once you've joined the conference.
Chrome Microphone Permissions
Firefox Microphone Permissions

Speak a few words and if you hear audio, click the Yes button . To choose a different microphone and repeat the audio test, click the No button . If you need help with your hardware, click the Question Mark icon .
Use Conference Interface
The conference interface contains a variety of tools to help you moderate your presentation. Each area of the interface is created within its own window and can be resized.
Moderators have improved functionality and control for recording conferences. Instead of starting the recording immediately after the first user has joined, conferences includes a start/stop button so moderators can control the length of the recording. After the conference session is over, the recorded segments will be published as one recording.
After joining the conference and setting up your microphone, moderators receive a reminder notifying them that they can record the meeting, but they must click the recording button to start the recording.
Note: You must select the record option when creating your conference in order to see the recording button.
The Users panel  displays the users in the conference. To locate the presenter/moderator, look for the presentation icon next to their name. When you are the presenter/moderator, you can switch the Presenter by highlighting the name of a user in the User list and clicking the Change Presenter button .
You can mute or unmute yourself, and if you are the moderator/presenter, you can mute everyone . You can also kick a listener out of the conference by hovering over the listener's name and selecting the x that appears to the right . The lock icon  indicates the moderator has locked viewers from accessing certain features.
At the bottom of the Users panel, click the user settings icon  to Clear all status icons, Mute All Users, Mute All Users Except Presenter, or Lock Viewers.
Sharing Media Tools
In the left corner of the title bar, you can share your desktop , join/leave audio , share your video (webcam) , record conference , and mute or unmute yourself .

Resize Conference Windows
Each window within the interface is independent of the others. You can resize the windows to personalize your viewing experience. To change the size of a window, hover over the edge of a window until the cursor becomes a double arrow, then click and drag to your desired size.
To leave the conference, click the log out button or close your browser tab or window.
