Why These Tools
Silence on a call is usually a settings problem, not a broken microphone. Mic Test shows in a few seconds which device the browser is using, how loud it is in dBFS, how much background noise comes with it and whether loud passages are clipping, then plays back a short clip so you hear the result yourself.
Camera, speaker and connection checks will follow, aimed at the minute before a meeting starts.
