Writers zoom session

It's only the second time I've ever done this. Seemingly when I spoke they couldn''t hear me, and I was asked to turn the video off. I think I must be doing something wrong, or else I have a cheaper laptop than everyone else. The meeting went on for nearly three hours. I kept looking at the red button that said: 'Leave Meeting.' One of my colleagues was equally bored, and kept sending me wee messages.
