When a Zoom session is running in a classroom, multiple participants within the same physical space (classroom) may need to join the meeting (rather than simply share their screen). When this is the case, it is important that only one Zoom participant in the physical classroom is connected to audio (this is most often the instructor / podium computer). Any in-class participants who wish to join the Zoom meeting should follow these steps:
Step 1: Join the Zoom meeting.
Step 2: Immediately “Leave Computer Audio”
Until this step is done, you may experience echo / feedback noises.
Simply muting your microphone will not fix audio problems; you must “Leave Computer Audio” to eliminate potential problems.
