Test audio and video

I'm scheduled to present at 9am and can't risk tech problems. Run an audio and video test: confirm mic picks up my voice clearly from one foot away, confirm camera is at eye level and shows my upper torso, check speaker output so I can hear others, and report any warnings about bandwidth or hardware conflicts. Do this fifteen minutes before the meeting.

Before I send the all-staff calendar, make the test experience simple: surface the pass/fail for mic, camera and speakers up front, show the detected network upload speed, flag anything that will block recording or screen share, and list the single obvious fix for common failures like muted mic or wrong camera selected.

I joined the weekly training and my mic meter shows activity but I can't hear others and they can't hear me. I tried switching devices but I'm not confident which indicator matters. What is the most likely diagnosis and the fastest sequence of checks to restore both incoming and outgoing audio without leaving the meeting?

Every session I lose 10–15 minutes troubleshooting audio or video: swapping cables, rebooting, rejoining. I run remote classes three times a day. Where am I wasting time and what three pre-meeting checks or habits should I institutionalize so I stop cutting into class time?
