Disable background noise cancelling in Team

EWernars 

The only response you would hear from Microsoft would be to use devices that they have certified, these kind of issues are the reason they need to have a certification process. I have a decent Blue Mic and DSLR Camera sat beside me I use for YouTube, but I use a certified webcam and speakerphone for Teams calls to ensure it's totally reliable.

There is one exception, in a Live Event where you could well be receiving an audio feed from professional equipment there is a switch within the meeting called Auditorium Mode that adjusts the noise cancellation. Unfortunately you can only use it in a Live Event.

Here's the list of certified devices
