I'm using the headset and Surface device provided to me by the House of Commons. I'm using only House equipment, and I've never had a problem before. As you know, we met via Zoom for two years, and there was never an issue with the equipment. If my device is defective, they will have to send me a new one.
I'm not a computer technician, so I won't attempt to diagnose the problem, but I can tell you that I'm doing what I've been told to do, as we are all asked to do when participating virtually.
