I'm using a MacBook Air (Retina, 13-inch, 2019) with the intel i5 processor. My zoom client and macOS are fully updated to the latest versions. I have "Suppress background noise" set to "High" and have had it this way forever. The "Show in-meeting option to enable Original Sound" is no checked in my audio settings.
Any yet, it seems that background noise suppression is not working, when I'm using the MacBook speakers/microphone or when using Apple earpods with their mic. It worked fine up until a couple of months ago. Now, my zoom room members can hear people talking in the offices, hallways, etc. that are next to me. I've tried it all, so it seems, and can't figure out why it isn't working.
Thanks for the info! Unfortunately, that was the first thing I looked at, and the box is already unchecked. 😞 So I'm still back to square on on this with no help from Zoom tech support. I've even reinstalled the Zoom client on my MacBook. No help.
