Audio grayed out during webinar cannot share audio

[spaint77]

During a recent webinar my mac pro was alternative host. I was not able to choose share audio. I am reading in the community that the multiple sharing needs to be changed to single sharing.

Will zoom please add a tool tip in app for this? The current in app info tool was not clear about the problem or the solution. Any changes to this application where a solution is explained are welcome. Even at the bottom if the share window....But the multiple share and single share needs a chart or something so that non engineers can understand the features without reading 10 pages of text. And this feature of sharing audio is used frequently by users/ panelists/ co-hosts in webinars who did not create the webinar themselves. Thank you for considering these ideas.
