Sem audio no Zoom, Teams ou Google Meet? Solucao

You join the call, you can't hear anyone, or they can't hear you. The most common cause is that the conferencing app picked a different mic or speaker than the OS default. This guide fixes audio in Zoom, Teams, and Google Meet.

Test Your Mic and Speakers First

Before troubleshooting the calling app, confirm the hardware works at the OS level. If our test shows your mic working but Zoom doesn't, the problem is inside Zoom: not your mic.

Zoom Audio Settings Walkthrough

Open Zoom → click your profile picture → Settings → Audio. Verify "Speaker" and "Microphone" dropdowns show the device you actually want. Click "Test Speaker" and "Test Mic": both should produce clear sound and a moving input meter.

If the mic input meter doesn't move when you speak, try a different device from the dropdown. Many laptops have multiple "microphone" entries (built-in, webcam mic, Bluetooth headset) and Zoom may have picked an inactive one.

Microsoft Teams Audio Fixes

Click the three dots (top right) → Settings → Devices. Check the Speaker, Microphone, and Camera dropdowns. Teams shows a live mic preview: speak and watch the meter.

If "Make a test call" is grayed out, your Teams admin has disabled it. Use our online mic test instead to verify the hardware.

Teams sometimes caches the wrong default. Quit Teams completely (right-click tray icon → Quit) and reopen.

Google Meet Audio Fixes

In the call: click the three dots → Settings → Audio → Microphone and Speakers dropdowns. Pick the right devices.

Meet runs in your browser: so Meet's mic access depends on browser permissions. Click the padlock icon → Site settings → Microphone → Allow. Reload the call.

Browser Audio Permissions for Web Calls

Chrome: padlock → Site settings → Microphone + Camera → Allow. Edge: same. Firefox: padlock → "Connection secure" → More information → Permissions.

Once changed, you usually need to reload the call. Some sites also require closing and reopening the tab to pick up the new permission.

Headset and USB Mic Not Detected in Call Apps

USB mics and headsets sometimes connect after the call app has already launched, so the app missed them. Quit the app fully, then plug in the device, then reopen.

If the device shows up in Windows/Mac sound settings but not in Zoom/Teams, reset the app's audio cache: in Zoom, Settings → Audio → click "Same as System" to force re-detection.

Echo, Feedback, and Background Noise Fixes

Echo: someone else is using speakers instead of headphones. The mic picks up the speaker output and sends it back. Fix: ask the affected person to use headphones.

Feedback: your own mic is too close to your speaker. Move further apart, lower speaker volume, or use headphones.

Background noise: enable noise suppression in your app. Zoom: Audio → Suppress background noise → Auto or High. Teams enables this by default.
