Audio cracking on Zorin OS

Operating system: Zorin OS 16 Core

Zoom version: 5.12.9 (367)

When I share a video, an audio or a presentation with audio,  the audio starts cracking. This doesn't happen when I stop sharing screen. Any ideas how to solve this issue?

I think this is a problem with Linux because on Windows it works well. I really need to solve this since I work mainly on Linux and it's a pain to be changing from Linux to Windows each time I have to give a class.

Thanks in advance.
