Zoom Microphone Not Working?

1. Connect to meeting audio

Look at the meeting controls. If you still see Join Audio, use it to connect with computer audio or the equivalent device-audio option. Joining the video meeting and joining its audio are separate steps.

Once connected, check the microphone button and any physical mute switch. If Zoom will not let you unmute, ask the host to check the meeting's mute controls. On a phone, Zoom may describe internet audio as Wi-Fi or cellular data; wording varies by app version.

2. Check the same microphone outside Zoom

Run the Microphone Test. Start it, allow browser access and select the input you intend to use. Speak, watch the level and play a short recording where supported. Stop the test before returning to Zoom.

• Your recorded voice is audible: compare the input name with Zoom's selection. The two applications may use different devices.
• The browser refuses access: fix that browser's permission. This alone does not establish whether the Zoom desktop app is blocked.
• No microphone or a silent recording: check connection, input choice and physical mute. Try the broader device checklist before treating this as a Zoom-only problem.

Use Microphone Not Working for the missing or silent-input branch. A level that moves with background sound is not proof that your spoken voice is clear.

3. Test the input in the Zoom desktop app

1. Open Zoom's settings from your profile menu and choose Audio.
2. Select your intended microphone, then run the microphone test. Speak normally and listen to its recorded playback.
3. If the recording is silent, choose another available input and repeat. If you cannot hear any playback, test the speaker separately before deciding the microphone captured nothing.

You can also use the audio selector beside the meeting's mute control to change devices during a call. Recheck this after connecting or reconnecting a headset.

For a very quiet or distorted sample, review the input level rather than raising the speaker volume. Zoom provides microphone level controls and an automatic adjustment option. Retest after changing one setting.

4. If you joined Zoom in a browser

The Zoom Web App has its own audio settings, including microphone selection and a recorded mic test. Open its Settings panel, find Audio and use those controls to check the selected device.

Allow microphone access for the Zoom page in that browser. In Chrome, inspect the saved microphone permission through site settings. Reload the meeting page after changing a blocked permission.

The browser also needs operating-system microphone access. Permission for the desktop Zoom app does not grant it to the browser, and permission for Device Tests does not grant it to the Zoom website.

5. Check Windows or Mac permission

Windows 11: in Settings, open Privacy & security and find Microphone. Check microphone access and the relevant app controls. A desktop installation or desktop browser also requires desktop-app access.

Mac: find Microphone under Privacy & Security in System Settings. Allow Zoom if you use its app, or allow the browser you use for the meeting. Follow any prompt to restart that application.

If the microphone does not appear in Zoom, reconnect it and inspect these permissions. An organisation-managed setting may require help from your IT team.

Using Zoom on a phone?

Connect meeting audio, unmute and allow Zoom to use the phone's microphone. Check the app's microphone permission in your phone settings; the exact menus vary by operating-system version and manufacturer. Reconnect your intended headset if needed.

A mobile browser test checks the browser route. Return to the Zoom app and confirm your voice in a meeting after changing its permission.

6. Verify what the other person hears

Repeat a short sentence in Zoom after each change. A clear recording in Zoom is useful evidence that the app received your voice, but it does not test everything between you and another participant.

If local playback is clear and the live meeting still breaks up, keep that distinction when asking for help. The problem may involve the meeting or connection, and a browser meter cannot identify it. Run the Video Call Test for separate local camera, microphone and speaker checks, then verify the complete call with another participant.
