Test Your Audio and Video
It is not possible to do test runs of each session. However, there are still lots of ways you can test your equipment to be sure everything is working properly.
Visit https://zoom.us/test to join a test meeting, then follow the instructions to test your video or audio. If you are a presenter, also test the Share Screen option.
What you need:
webcam / camera on your device
headset (or speakers and microphone; this helps you avoid echo and stay muted)
reliable internet connection (bandwidth requirements)
Video helps keep virtual sessions personal. With video enabled, presenters can respond to verbal cues, body language, face-to-face communication, and other factors to make them feel that they are right there in the room with you.
In a virtual session (Zoom meeting), you can see other participants' videos and they see yours—just like you see other session attendees in a physical room. The host may ask you to unmute your microphone to ask a question. Ensure your microphone is muted if you are not talking.
A webinar on the other hand is a one way broadcast—attendees listen to the live speakers without seeing the attendee list. A webcam is not necessary if you are attending for a webinar.
Virtual Session Toolbar
From the bottom toolbar in Zoom, you generally can:
As a general tip, we recommend closing all other applications on your device not needed for the virtual session.

I can't hear the speakers/participants.
Have you joined the audio section?
Is a speaker or headset connected to your computer?
Others can't hear me.
Check if your microphone is connected and still on mute. Unmute before speaking.
Why do others hear an echo when I talk?
Someone has their speaker and microphone causing an echo. Please ask all participants to mute themselves or ask the host to mute all participants.
I hear an echo when others are talking.
There is nothing you can do other than asking for the speakers to use a headset, adjust their microphone sensitivity, and all other attendees to mute their microphones. Learn more about solving echo issues with Zoom.
When joining a virtual session on a desktop or laptop computer, please ensure you use a supported browser, preferably Google Chrome, to properly hear the session audio.
Check your version of Chrome and ensure you are upgraded to the latest update.
If you are not on a supported browser, you may receive an error message.
Please refer to Zoom's supported browser page for an updated list of all supported browsers.
The other participants can't see me, or my video is not showing.
Ensure that the correct camera is selected and that you have chosen to "Start Video" from the toolbar. If the problem persists, please refer to My Video/Camera isn't working for solutions.
