Another source of audio echo in a meeting

[RobRansom]

I read a good article here about “Managing audio echo during a meeting”.   That article presents three ways that echo could be coming into the Zoom meeting.  I would like to add that there is a fourth way that can happen.

Recently, I was leading a hybrid meeting (at a physical location and over Zoom). One of the Zoom participants was driving his car and using his phone to listen to the meeting.  He was using CarPlay in his car in order to hear the audio clearly.  The “echo chamber effect” was intense!  

Once he arrived at his destination and dropped off the call the problem was immediately resolved. (Unfortunately, I was leading the meeting and the only tech person available - so it took longer than it should have to kill the echo.)
