Ah could be hardware/OS, yeah. I believe everyone at our company are on MacBooks (I’m a Linux guy myself, but orgs don’t usually like that).
My personal laptop is a Dell XPS 13 and while I like it for various reasons, it has had plenty of problems with the built-in mic and video (mostly the mic). So it very well could be that.
There’s no need for a bicameral system. It was a system designed to capitulate to wealthy interests and nothing more.
