Zoom Can’t Hear Me: 7 Fixes That Actually Work

You join the call, say hello, and nobody answers. Then somebody types in the chat: “We can’t hear you.”

It’s annoying, but it’s rarely a dead microphone. Most of the time it comes down to a setting. Zoom is listening to the wrong mic, a permission got switched off, or another app is holding onto the device. The seven fixes below go from quickest to slowest, so you can stop as soon as one works.

Do this 10-second check first

Before you change anything, find out which side the problem is on. Open our free microphone test, allow access when your browser asks, and say a few words.

If the line moves, your mic and your browser are fine, and the problem is inside Zoom. Start with fixes 1, 2 and 5. If it stays flat, the problem is in your system or the hardware, so jump to fixes 3, 4, 6 and 7.

Fix 1: Make sure you’re really unmuted

Yes, really. It catches people more often than any other cause.

Look at the microphone icon in the bottom left corner of the meeting window. A red slash through it means you’re muted. Click it once.

A few things look like a broken mic but aren’t:

1. There’s no mic icon, only “Join Audio.” You haven’t connected your audio yet. Click Join Audio, then choose Computer Audio.
2. The host muted everyone. Some hosts also switch off the option to unmute yourself. If clicking does nothing, ask in the chat.
3. Push-to-talk is on. If “Press and hold Space to temporarily unmute” is enabled in Zoom’s audio settings, you have to hold the space bar while you speak.
4. A physical mute. Some headsets have a switch on the cable, and some laptops have a mic mute key on the top row. Check that too.

Fix 2: Pick the right microphone inside Zoom

Zoom doesn’t always use the mic you think it does. If it’s set to “Same as System,” it follows whatever your computer calls its default. That could be the built-in laptop mic under your keyboard, or a webcam you never use.

Click the small arrow next to the mic icon and choose your headset or USB mic from the list. Then open Settings, go to Audio, and press Test Mic. Say something and watch the level bar. If it moves, Zoom can hear you.

While you’re on that screen, two other settings are worth a look. Turn off “Automatically adjust volume” and set the slider yourself, because the automatic setting sometimes drops the level so low that you sound far away. And set “Suppress background noise” to Auto, since the higher settings can clip quiet voices.

Fix 3: Let Zoom use the microphone in your system settings

Both Windows and macOS can block an app from the mic, and neither makes it very obvious.

On Windows 10 and 11: open Settings, go to Privacy (it’s called Privacy & security on Windows 11), then Microphone. Three switches matter: Microphone access, Let apps access your microphone, and Let desktop apps access your microphone. The Zoom app counts as a desktop app, so that last one is the one people miss. Turn all three on.

On a Mac: open System Settings, then Privacy & Security, then Microphone, and switch Zoom on. (On older versions it’s System Preferences, then Security & Privacy.) macOS will usually ask you to quit and reopen Zoom, so do that. If Zoom isn’t in the list at all, quit it and start a meeting again, and macOS should ask for permission.

If you use Zoom in a browser: click the padlock or settings icon next to the address bar, find Microphone, set it to Allow, and reload the page.

Fix 4: Check the input device and volume in your system

If the mic test on our page showed a flat line, this is the next place to look. The wrong input device, or a volume of zero, will silence you everywhere.

On Windows, go to Settings, then System, then Sound. Under Input, pick your microphone, speak, and look at the bar under “Test your microphone.” It should jump around. If it doesn’t, raise the input volume.

On a Mac, go to System Settings, then Sound, then Input. Choose the right device and watch the input level while you talk.

One more Windows trick. Open More sound settings, switch to the Recording tab, double-click your mic, and open the Advanced tab. If “Allow applications to take exclusive control of this device” is ticked, untick it. That stops one app from locking the mic away from the others.

Fix 5: Close other apps that might be using the mic

Teams, Discord, OBS, Skype, a second browser tab with another meeting open. Any of them can hold the microphone, and some drivers won’t share it.

Look for the small mic icon in the Windows system tray, near the clock, or the orange dot in the Mac menu bar. Both appear when an app is using the mic, and on Windows you can hover over the icon to see which one. Quit the extras, then leave and rejoin your Zoom meeting.

Fix 6: Sort out your Bluetooth headset

Bluetooth headphones usually have two modes. One is for music: good sound, no microphone. The other is for calls: lower sound quality, microphone on. Sometimes the computer sticks with the music mode, and Zoom finds no mic to use.

Try this:

1. Open your system’s sound settings and look for the headset or “Hands-Free” version of your device. Choose it as the input.
2. In Zoom, pick that same device under the mic arrow.
3. Still nothing? Turn the headset off and on, or remove it from your Bluetooth list and pair it again. Check the battery too.

The sound will get a bit worse once the mic is on. That’s normal, not a fault. To rule Bluetooth out completely, plug in a wired headset for one test call.

Fix 7: Update, restart, and only then reinstall

It’s the boring one, and it works more often than you’d expect.

First, update Zoom. Click your profile picture in the app and choose Check for Updates. On Windows, update the audio driver next: open Device Manager, expand Audio inputs and outputs, right-click your mic, and pick Update driver. If that changes nothing, choose Uninstall device and restart the computer, and Windows will put the driver back on its own.

Then restart the computer anyway. A full restart clears audio services that get stuck. If you’re still silent, reinstall Zoom as a last resort, using the latest version from Zoom’s official site.

How to know it’s fixed

Run the microphone test once more. The line should move as you talk, and Test Mic in Zoom’s audio settings should show the same thing. For a final check, start a meeting by yourself, record it, and play it back. You’ll hear exactly what everyone else hears.

If a different app can’t pick up your mic either, the problem is probably the hardware or its driver, not Zoom. Try another headset or a USB mic. Our Zoom mic guide walks through the same steps with a checklist.

Quick answers

Why does my mic work in the browser but not in Zoom? Zoom has its own permission and its own input setting. The browser can be allowed while the Zoom app is blocked, or Zoom can be pointed at a different mic. Fixes 2 and 3 cover both.

Why do people say I’m too quiet? Check your input volume in Windows or macOS, and turn off “Automatically adjust volume” in Zoom. Distance matters too. About a hand’s width from the mic is a good starting point.

Do I need to restart Zoom after changing permissions? Usually, yes. On a Mac, Zoom will ask you to quit and reopen. On Windows, leaving the meeting and reopening the app is the safe move.
