Whenever I host a meeting the audio doesn't work for anybody. I can't hear them and they can't hear me.

All my audio settings are normal. The weird part is when i join someone else's meeting the audio is all good.

Not sure what to do, If you know what's up please help. 
Thank you.

Most of my days I am booked in back to back meetings on the half hour. If a meeting is running over, my next meetings participants are able to join. How do I disable that? I've enabled the waiting room setting, but that is not doing the trick. I want to be able to stop the next meeting attendees from joining a call that is running over. 

In a recent 2-person Zoom call, the host was unable to unmute himself.  He found his mute icon and made sure he wasn't muted, but I still couldn't hear him.  I can speculate that his microphone was simply broken or disconnected from his computer, but this was a regularly practicing lawyer, so that seems unlikely. I'm wondering if there is an alternate explanation.

If there is, I need to know, because I'm new to Zoom, and about to host a large family meeting. It would be embarrassing if nobody could hear me.

I recently purchased a Pro account.  I'm trying to figure out how to add one tap information to the meeting invite so people w/o the ability to use video can dial in by phone.   I have enabled both phone in the meeting setup.  But how do I get zoom to generate an invite that I can copy paste with one tap dial in?

When creating a zoom meeting (using my browser and without calendar integration) I used to be able to copy the invitation, and the invitation had a hyperlink for One Touch dialing. Now it no longer has a hyperlink for One Touch dialing in, and the meeting link itself is also no longer a hyperlink when I copy paste the meeting invitation. Did something change? Is there somewhere else I can get those links easily? It's a lot of extra work now to simply share out meeting information after I create a meeting. 

Hello,

I am attempting to disable the copy/paste feature for my Mac endpoints. I have tried pushing a config profile but none of the available keys I have been able to find pertain to disable copying and pasting. I have referenced this document https://support.zoom.us/hc/en-us/articles/115001799006-Mass-deploying-with-preconfigured-settings-for-macOS but it doesn't appear to have the correct keys. I know this can be done but I don't remember how it is handled. Any support would be appreciated.
