Reasons for an echo or feedback:
- Echo occurs if input output audio devices are placed close together. Someone's computer speakers are too close to their microphone or their audio is too loud.
- Being in the webinar twice. If you hear an echo and notice that someone is in the room twice, that maybe the cause.
- Having multiple people in the same physical office or room in the same web conference room (sound from the speaker on one computer enters the microphone of the other computer).
- If you or someone else is in the room twice; remove them, exit or close any extra windows or tabs.
- Refresh the page.
- Move your microphone away from your speakers.
- Mute or turn off the microphone of the person who is causing it or mute yourself if you are the cause. Mute others when they are idle.
- Have the person who is causing it, turn down their computer's volume.
- If multiple people are on multiple computers in one physical location, have them go in separate rooms or turn off or mute all the computers but one.
- Mute yourself when you play a YouTube video.
- Buy or use an external microphone. Built-in mics quality can vary.
- Turn off webcams. This will allow more bandwidth for audio.
