When broadcasting a webinar, once the live speaker starts presenting our pre-recorded video - users can not hear the pre-recorded video.
Specifics of situation -
It is only happening to one business/agency.
Everyone from this agency can not hear the pre-recorded video but they CAN hear the live speaker.
What we have tried-
We have tried using both browser and desktop app
We have tried whitelisting the domains listed on the website
We have tested this out with multiple people from their org
We have triple checked audio settings/devices
Any ideas would be helpful please.
