Zoom whiteboard

Q: is it possible to lock the other pages so that my participants can only view the page that I am on as you are able to when you normally share screen? 

A: No, we can't.   participants can still see other pages if someone is presenting.  And nobody can lock the pages. The feature is not supported yet (2023/07/27)

Q: Can I share my computer sound while presenting/collaborating my Zoom Whiteboard? If so, how? 

A: out of meeting, no.    inside meeting, yes.   

How to do ? We can click the "Meet now" button. Then we can collaborate on the same doc and share video/audio.
