Zoom microphone not working?

Run a controlled microphone test

Open MeterSee's microphone test, allow access, speak normally for 5–10 seconds, then stop. Record the active device name, peak level, noise floor, and any clipping warning.

• No device opens: focus on permission, a busy device, cable, Bluetooth, or operating-system privacy controls.
• The meter moves normally: focus on Zoom's selected input and Zoom audio settings.
• Signal is very low or clipping: fix input gain before judging Zoom noise suppression.

Select the exact tested device in Zoom

1. Open Zoom Settings, then Audio.
2. Under Microphone, choose the same device name shown by MeterSee instead of relying on System Default.
3. Use Zoom's Test microphone control and confirm that playback contains your voice.
4. If a Bluetooth headset exposes separate profiles, compare the headset input with the computer microphone and keep the clearer path.

Check permission at both layers

1. In the operating system's Privacy or Security settings, allow microphone access for Zoom and your browser.
2. In the browser address bar, confirm MeterSee is allowed only for the test; a browser pass does not automatically grant Zoom desktop access.
3. Quit and reopen Zoom after changing operating-system permission.

Remove conflicts and processing variables

1. Close other meeting, recording, streaming, and voice-control apps that may hold the input.
2. Disconnect and reconnect the microphone, then select it again in Zoom.
3. Temporarily return Zoom microphone processing to default. Do not raise every gain control at once.
4. Restart the computer only after recording the before-and-after device name and signal result.

When hardware service is reasonable

Escalate only when the same input fails in MeterSee, the operating-system input meter, and another known-good application after cable, port, and permission checks. A healthy MeterSee result alone does not prove Zoom is configured correctly.
