wait what, are you using the DOS-zoom client? Or how is it, that everyone else got general drivers for their devices so applications can use standardized APIs and "just work"
If you've never been on a conference call where someone can't get their dial-in, audio, camera, screen share, or mute button to work, I'd suspect you've never been in a conference call. These recurring issues are fewer with Zoom. I spent 6 hours on zoom today (ugh), and every day I'm in a 25-to-50-person call that has consistently been buttery smooth.
