Hearing an ECHO feedback on your Audio during LIVE Events.
1. Your speaker volume is at maximum.
2. Your Computer Sound Settings may need to be adjusted.
3. A recent Browser or Device update may have caused some tweaks into your configuration
How to avoid and/or Eliminate this?
1. Double-check that you’re speaking into the correct microphone.
2. Wear headphones or Earbuds to avoid looping your audio back to your mic.
3. Make sure you are not Joined in as another presenter or attendee on that same Device. Having a different browser tab as a 3rd person audience may also result an Audio feedback loop.
4. Mute yourself if you are not speaking and tell your co-presenters to do the same.
5. Use a noise cancelling Audio device.
If you continue to face the same problem, you may have to make some adjustments with your audio device properties. Some sound-cards employ a Windows feature called "Microphone Boost" that Microsoft reports may cause an echo. To reduce the boost levels, Click the "Recording" tab, and then right click on your headset and select "Properties." Click the "Levels" tab in the Microphone Properties window and reduce the "Microphone Boost" Level.
It may also be related to your Audio Enhancement Setting. You can try to remove this by going to:
Open the Control Panel and click on Sound.
Select the Recording tab, right-click the microphone being used, and select Properties
Select the Enhancements tab, disable all enhancements, and click Apply.
Another Thing :
If there’s a “Noise Suppression” or “Noise Cancellation” option, enable it. Other options here may also help reduce background noise—for example, on the PC we tested this on, there was an “Acoustic Echo Cancellation” option that would help reduce echo caused by speakers if you’re not wearing headphones.
Click “OK” to save your changes and close the window.
