MacBook Pro 16" Random Scratching Noise from the Speakers

I bought a new MacBook Pro 16" a few days ago that is running MacOS Catalina 10.15.4.

A strange sound comes from the speakers every 2-3 minutes.

This is not like the "popping" sound frequently mentioned on the Internet.

It also happens when the music is not playing or the device is on standby.

When I decrease the volume it also decreases and when I mute it disappears completely.

Here is a 2-second recording of the noise:

I don't know if it is a software or hardware issue. I'm wondering if anyone else is experiencing the same problem.

Thanks!

It is solved! Microsoft Outlook mail client was causing the issue. I don't know why but I discovered it by chance after a restart. I could also reproduce the issue by quitting the mailing app and re-logging in a few times. Phew! It seemed so random and hardware related. Fortunately, it wasn't :)

Wipe your drive clean and reinstall the OS. I have the 16" and have never experienced this. Might be a corrupt file. If you're going to do the full wipe and install then don't install any apps outside of what comes built-in with the OS. Do some testing from there.
