I have a problem with sharing videos on my Xiaomi pad 5. When I share the screen, I activate the "share audio" option, but when I start a video the other participants cannot hear the audio. I have tried everything but with another device and it works fine. How can I fix on my Xiaomi pad 5? Thank you

When I'm screen sharing, the preview section in the top right corner doesn't show up and I can't enable it anywhere. Because I want my video to appear as a large icon on the right or left side, not as a small icon on the right or left side

I'm using Zoom on Linux. I do have an LED light that I want to switch on/off whenever I join or leave a zoom meeting. 
I guess this can be solved by some code listening for certain dbus events.
Before reinventing the wheel I wonder if this has already been solved. 

Never mind... I found a list of Zoom certified cams and chose one of them.

I was all set to buy a webcam for an upcoming Zoom meeting, then I read a review that said "Zoom etc. won't recognize the camera if the AnkerWork software is open; it 'possesses' the camera, so there is no adjusting the image if the camera is in use, effectively."

I want to be able to use webcam software to adjust things while using Zoom. And I'd like to keep the price around $100 or less. Must work with Windows 10 and 11.
