Echo is caused by audio looping back via remote participants’ speakers and into their microphone. When on calls with echo, always stop and ask who hears it. If you hear echo, then you are NOT the source of the echo. The person who does not hear echo is the source. It is a bit backward from what you might think. The exception is if more than one source is causing the echo.

Everybody hears an echo when they speak?

  • Echo is being caused by multiple participants, including the meeting host (yourself).
    • Start by resolving the host’s cause of inducing echo by following the remainder of the flowchart tree.
    • Then, as host, have all remote participants mute their microphone in the VidyoDesktop application toolbar.
    • Have remote users un-mute their microphone one at time until you find each user who is causing echo. Follow the remainder of the flowchart tree for each user causing echo.
    • Alternatively, as the Meeting Room owner/Operator/Admin, use the Control Meeting page of the Portal to control the Muting and UnMuting of each participant.

Everybody hears an echo except 1 User?

  • The participant doesn't have a Headset, or Speakerphone with built-in echo cancellation?
    • Enable "Echo Cancellation" in the VidyoDesktop application Configuration under Devices.
    • Alternatively have the participant use earphones to physically isolate the audio.
  • The participant does have a Headset, or Speakerphone with built-in echo cancellation?
    • Verify that the correct speaker and microphone devices are selected in the User’s VidyoDesktop application Configuration under Devices.
    • HINT: Have the participant tap the microphone they believe they are using to verify the device.
    • Have the participant choose appropriate devices (Headset or Echo Cancelling Speakerphone), and Save.
    • If the participant does not have a Headset or Echo Cancelling Speakerphone, return to previous question. Note: the built in camera mic does not provide Echo Cancellation

Is there still an echo?

  • Check the following:
    • VidyoDesktop Speaker and/or Mic volumes – lower each if high. High levels can overdrive the devices.
    • Device Speaker and/or Mic volumes - lower each if high. High levels can overdrive the device.
    • If using AEC Speakerphone, be sure device is clear of any obstacles. Paper, books, shelves, etc that are sitting on top of or too close to the device may cause feedback

If you are still unable to resolve the issue, it's time to contact our experts to further assist.
