I receive still a message about buffer error. Have you someone an idea, please?

Are you seeing an error for video being unable to play on the webcam or are you seeing the webcam as not Being Detected?

I am looking for a camera which was not detected. Exactly: it seems that a camera is detected, but not activated due to an error "buffer..."

I found this from a websearch, I am wondering if it fits your situation: [Workaround] Cheese Blank Screen or Display Corrupted in Ubuntu 22.04 | UbuntuHandbook

Edit: I just noticed that the link refers to Ubuntu 22.04 wheras ZorinOS16 is based on 20.04.

I tried this, but not working.

What means exactly? In my case this webcam issue was easy to fix, it simply wasn't being loaded by my BIOS settings (CMOS Camera), probably I disabled it when I was using Windows before replacing it with Zorin. You can check if it's disabled on the BIOS, but only if you know how to check safely, if you're not good at it better not.
