I have tried to use an ATEM Mini Pro and an ATEM Mini Extreme ISO with Microsoft Teams. Teams shows the ATEM as an audio input, but when I get into a presentation or try to make a test call, there is no audio. The ATEM audio works brilliantly in every other video conferencing app, including Zoom and YouTube. If I change the input to my native mic (Microsoft Surface laptop) it works in Teams. I can't figure out why Teams recognizes my video but not my audio. I have had my IT staff and the Blackmagic engineers looking at it for months to no avail.
