AUKEY-Webcam does not work in MS Teams on MacOS anymore

haukew I am having the same problem and happened upon a workaround.

After launching Teams and entering the meeting, I see a black screen where my camera feed should be (note I also see this in the preview before entering). If I launch FaceTime (possibly any other app that loads the camera), let the camera feed come up there, and then close it, the camera feed in Teams starts to work. Note this has to be done every time I enter a meeting.

Not ideal, but better than not having video or having to keep my laptop open.

I hope MS fixes the underlying issue soon, but hopefully this works for you in the interim and helps you (and any others in this thread) get by.
