Audio Sharing Sound Quality Problem

I’m reaching out to report an issue we've been experiencing during our Zoom calls. I use Zoom pro to film my short film and there was a problem today. During our session, there is a persistent crackling noise/ buzzy noise that disrupts the audio. Everyone here probably used a PC or a laptop but we all use our phones. All users have checked their equipment, and we’ve restarted the call multiple times, but the issue persists.

It appears the noise may be coming from within the Zoom system itself. This has made it difficult to conduct our meetings effectively.

Could anyone please assist us in identifying and resolving the issue?

The problem I experienced was resolved by updating Zoom software on my laptop computer.

"crackle" or "buzz" are words commonly used with external microphone connections;  if using a built-in microphones, I don't know what would cause that.

don't know if this will help... but my wife recently had a similar issue. she was facilitating a meeting and everyone went on break, away from their computers/phones. when it was time to come back, she wanted to share her Spotify ("Computer Audio" only) to alert participants that the break was over. the music was all garbled and crummy sounding, going in and out, almost like something was trying to noise suppress it.

turns out, something WAS -- she had VOICE ISOLATION turned on (I think maybe zoom auto-turned it on). once i set it to STANDARD, everything worked fine. btw, you have to actually share your screen, audio, etc for that orange icon to pop up in the upper right hand of your screen (by the Time & Date on Mac, don't know about Windows, maybe bottom right?)

hope this helps, i was pulling my hair out trying to find out why it was garbling her audio!
