QUESTION AND ANSWER
Can I change audio options after attendees have already joined?
Yes. If you have not started the webinar and change the audio options, any attendee who has already joined will remain connected via the option they chose. Example: webinar was scheduled to offer both dial-in and computer audio. Attendees joined early using computer audio. The webinar was changed to dial-in only before start. The attendees already joined via computer audio will still be joined via computer and will hear the webinar.
