Everything below has been checked and is in order.

Yet I can still NOT be heard in zoom meetings?

Check privacy settings

The sound is low and choppy, I can't hear what other people say even though the volume is max. I tried to test my speaker in the setting audio, but it is still small. Sometimes Zoom pops up this notification "Low system resources may affect your audio quality...", but I only open Zoom? This only happens in Zoom, other applications sound is still normal, proving that my speaker is fine.
My laptop is ASUS with Windows 11

Who can help meeeee

When my colleague attempts to share at the beginning of a meeting, the screen we see is black with a "[NAME] is sharing their screen" message. He tells me that his screenshare is paused, and he is unable to un-pause.

This happens consistently- the fix is for him to leave and rejoin the meeting. This consistently works, but is there anyway to identify and solve the root cause of the problem?

 We have 9 employees at my company and all have been going thru the following:

• Uninstalled the old version of Zoom, completed the cleansweep and reinstalled the Zoom from the download Center.
• Each new day, after exiting the application, the old version of Zoom reappears and I do the uninstall, CleanSweep and reinstall process again. The old version has an error message when we try to open it indicating we need to install an updated version and we need to contact our IT department to do this.
• I have run the uninstall via local admin rights as well as through my IT admin rights direct.  Same result. 
• I have uninstalled the zoom outlook app in the same manner.  Getting the same result
• I have rebooted in between the uninstall and reinstall.  Same result.
• Our IT has exhausted all of the potential know fixes on our end and deduced that it is a zoom issue we need to ID.

Help - anyone have this same issue??
