Hi,  I have been through countless settings and help sites and can't find the solution.

I am connected to zoom via my computer audio only.

I am using a microphone for my audio in and speakers for audio out.

All is well, until I share my screen.  Then my listeners get a huge echo.  So I mute my microphone and they can still hear me!

I can't seem to mute my microphone whilst sharing a screen.

I definitely don't have anything else picking up my voice connected to Zoom, so why is this happening? 

Big live presentation due in 2hrs, if anyone can help me I will be eternally gratefull.

Thanks

Hello,

I scheduled a meeting today with 2 other people. When the meeting started, none of us had audio. None of us were muted and I could not figure out what the problem was.

(We used our phones for audio, but it was annoying.)

My audio has worked until now. Any suggestions?

Hi, I wish to hold a meeting with around 200 people. I am having a zoom pro account.

How can I increase number of participants from 100 to 200/300?

I don't want to use webinar which has 500 quota since it is less interactive and need to add email address before getting in. I wish to use normal meeting with more participants. 

I normally save my meeting recordings to my laptop.  For the first time I am getting an error message saying "The specified procedure could not be found."

I see the video, recording, and audio icons, but they don't open.  Any idea what happened or how to retrieve it?
