Video problems

[Henrik8]

Here goes

I use zoom app on chrome OS on a Raspberry. When I start a meeting with my teacher she gets sound but no video.

If I join the same meeting with my laptop - no problem.

on the laptop I can see the video from my raspberry 

If I start a meeting with my laptop and invite myself on the raspberry, I have no problems.

What might the possible solutions be, to enable her to see video from my chrome OS?

Using the laptop is not a solution, since its too old and messes up the sound. Video on one device and sound on another is confusing to everybody
