Audio Echo for everyone except host

[os_shaneal]

Hello 

I’m reaching out regarding a technical issue we encountered during a recent webinar hosted by our company, and I’m hoping to get some assistance in resolving it for future sessions.

Here’s a summary of the issue:

• Whenever our executive, who served as the webinar host, unmuted themselves to speak, participants experienced significant feedback and echo.
• This occurred even though all participants were muted during the session.
• The webinar host did not personally experience any feedback or echo on their end while speaking.
• The host was using a laptop with built-in speakers and a built-in microphone in a private office environment.

Given that participants were muted, we’re unsure what might have caused the feedback. Please help in diagnosing and resolving this issue to ensure a smooth experience for all attendees in the future. I've looked at other articles on audio feedback resulting from a second device picking up sound but per the webinar host this wasn't the issue.

@os_shaneal - did you figure it out? It does not sound like a great experience. 
I was also thinking of the issue of another device in the same room, which you said wasn't the case. Could there by chance have joined both on web browser, and on the workplace app, on the same machine? 

For best audio quality, we recommend looking to get a headset or external microphone, since most built in laptop microphones just aren't as good. 

I wish you echo free future webinars!
