I have recently updated to Vegas Pro 19 full package and installed everything without thinking what I will use or not.
So I have Vegas Stream. I also happen to have multiple sound interfaces on my computer. And I use DroidCam as a webcam.
In a totally different context, I sometimes have remote meetings using Microsoft Teams (in browser, using Brave browser). In Teams screen to setup the devices before joining the room, my image is replaced with a sentence writton in white on black background saying something like "Please turn off Vegas Stream". If I switch my sound output from my usual sound card (Asus Xonar Essence STX) to the one were I have the headphones (some Realtek integrated to motherboard), then the "error" message goes off and the expect image from DroidCam appears. But if I join the meeting room without changing output sound card, then the other person(s) will see the "Please turn off Vegas Stream" message for the all meeting.
Why does this happen?
(Now I don't actually stream so I can't as well just uninstall Vegas Stream.)
