Google Meet’s green room can show whether the selected microphone receives sound before you enter a meeting. This is a local device check, not confirmation that another participant hears you. Use it to catch the wrong input, a muted headset, or a missing browser permission before the conversation begins.
Select the intended input
Open the meeting and stay on the pre-join screen. Below the preview tile, inspect the microphone selection and choose the actual device you want to use. Alternatively, open the preview’s settings and select the audio section. A laptop microphone and a headset microphone can appear as separate choices even when both are connected.
Speak and watch the meter
Use the microphone test and speak at a normal level. Google’s instructions say movement in the microphone bar indicates that the microphone works. If the bar stays still, check the selected device, its physical mute switch, and the relevant browser and operating-system permissions. Make one change and repeat the test so the successful adjustment is identifiable.
Confirm actual meeting audio
Join when ready and ask a colleague for a brief listening check. A moving local meter does not establish that a remote participant selected the correct speaker or that network audio is reaching them clearly. If necessary, compare the local result with what the other person hears. Avoid switching every audio setting at once or restarting during an important conversation without warning. Retain the working device selection for the session, and repeat the local check after disconnecting a headset, changing docks, or moving to another computer.
