What counts as a successful mic test?

A good pass means the browser can open the selected microphone, the meter reacts to your voice, and the recorded sample plays back correctly.

Why is the level meter barely moving?

The microphone may be muted, too far away, or set to a low input gain. Noise suppression can also make quiet speech harder to detect.
