Hi Fred,
I'm not quite clear on what you mean, sorry... But the steps would be that I have my screen share on and enable audio, and then go ahead as usual to press play on a YouTube video. All participants are muted except for me. The audio is clear on my side but students' expressions immediately tell me that the audio on their side is not working. They tell me it's an echo. Then, when I watch the recording later, I indeed hear only a garbled audio on the video portion where the sound is looping/repeating.
I could share my recording with you but I don't know how to download it off my LMS (Avenue).
TIA,
Crystelle
