Does Zoom discriminate voice handicap?

I've used Zoom for a few years (due to the pandemic) and I've had zero problems with being heard, even if I only have a voice whisper. I bought a new computer (Macbook Pro 14") and I've been in 4 meetings since and everyone complains about breakups in the sound, as if there's a glitch in my microphone. I've used both the internal microphone, a microphone I've hooked up through cable as well as a headset for bluetooth. Everything breaks up.

There's absolutely nothing wrong with the microphones, regardless of which. I've tested them all through voice memo as well as a service online, and it works fine.

However, when I test the microphone in Zoom settings, it breaks up when it plays back. And I wonder if theres's some *new* feature in the app that thinks my whispering voice is "noise" and is trying to silence me?

As I rarely have time to check before or during meetings, it's more or less me having to sit silent nowadays and I have no idea how to make my voice (even as weak as it is) heard again.

Can someone please guide me into how to set my microphone or audio settings, so people hear me and the mic do not break up my speech? Or is there's some settings at the other participants that is the issue here?

As I'm part of a scientific trial and also active in some organisations,  it is crucial to be able to actually be heard when we have meetings online as we are living far apart. 

My old computer (Macbook Pro 15" from 2012) never had any issues with the same setup I've had before, with the same microphones/headphones.

I'm more than frustrated, so please help!
