"Share Sound" option is grayed out when sharing screen.

Wow... thanks @Bri!!

I've been having this issue for a few weeks. As you probably know, I play around with my settings a lot.  Today I was putting together a demo for a new client, and wanted to record a "play video" in a Webinar with both Standard and Shared Screen views set for attendees.  No sound again!  (It hadn't really bothered me enough to investigate the last week or so.)

So I found this this post with your reply, and checked my settings:

Changed to "One participant at a time" and now it works.  I decided to test whether this can be done during a webinar....

Big note for anyone finding this solution during a live webinar:  You have to "End Webinar for All" and restart the Webinar for this to take effect!  (Note: if you Leave the webinar and there is nobody to assign as Host, your webinar will end.)  I tried assigning someone else as Host, exiting the webinar, then rejoining the webinar, and still had the issue.  You can immediately restart the webinar... but the new setting won't take effect until that occurs.

So TEST THIS BEFORE YOUR WEBINAR (like I'm doing today)!

I'm a long-time Zoom user and having the same issue for the first time - this is obviously something Zoom needs to fix because I have always enabled multiple presenters to share and it's never been an issue before. My presenters share one after the other and we need sound on their videos.

Can you please look into it @Bri 

I see multiple requests to resolve this issue, but the resolution is to eliminate the ability for multiple users to share screen - which is something I need.  Can someone explain what changes in a webinar that grays out the 'share sound' check box?  How can I maintain the ability to share sound AND also allow multiple users to share screen?
