Microphone Not Working

A microphone not working usually has a simple cause: the mic is muted by a key or switch, Windows privacy settings are blocking the app, or the app is listening to a different input. Those three cover most cases, and each takes under a minute to check. This guide goes from the quickest fixes to the rare ones, for Windows 11 and 10, Mac, iPhone, Android, headsets and the Dell, HP and Lenovo quirks. After each fix, run the mic test. If the meter moves when you speak, the mic works, and whatever is left is inside the app you use.

Quick checks

• A mute switch or key. Many headsets have a slider on the cable or a button on the earcup. Laptops have a key with a crossed out microphone: F4 on most Lenovo laptops and on Dell Latitude and Precision models, and F4 or F8 on HP. A lit key usually means muted.
• The app's own mute. Teams, Zoom, Discord and Meet each have a mic button. A crossed out icon means you are muted in that app, whatever Windows says.
• Unplug and plug back in, into a port on the computer itself rather than a hub. Then reopen the app, because many apps only list mics that were connected when they started.
• Restart after updates. A half installed audio update often finishes only on a restart. Sleep does not count.

Allow microphone access in Windows

One switch can block every app from the mic, and updates or privacy tools sometimes turn it off.

Windows 11:

1. Open Settings, Privacy & security, then Microphone.
2. Turn on Microphone access and Let apps access your microphone.
3. Turn on Let desktop apps access your microphone. Zoom, Discord, Chrome and Edge are desktop apps: they never appear one by one in the list, so this switch covers them all. Microsoft Teams has its own switch in the app list, and Microsoft says to turn on both.

Windows 10: open Settings, Privacy, Microphone. Under Allow access to the microphone on this device, select Change and turn it on, then turn on Allow apps to access your microphone and Allow desktop apps to access your microphone.

Choose the right input device

Each app can pick its own mic, so the meter can move in one place and stay flat in another.

• Windows 11: Settings, System, Sound. Under Input, pick your mic in Choose a device for speaking or recording, then select the arrow next to it for Input volume and Start test.
• Windows 10: Settings, System, Sound. Pick your mic in Choose your input device and speak: the Test your microphone bar should move.

Then open the app's audio settings and choose the mic by name instead of Default.

The level is flat or too low

Open the classic Sound window: in Windows 11, Settings, System, Sound, More sound settings. In Windows 10, Sound Control Panel on the Sound page. Use the Recording tab.

1. Find hidden mics. Right-click an empty part of the list and tick Show Disabled Devices. Right-click a grayed out mic, choose Enable, then Set as Default Device.
2. Raise the level. Right-click the mic, Properties, Levels. Set the slider to 80 or more and check its speaker icon is not crossed out. If you see Microphone Boost, try +10 or +20 dB. More boost adds hiss.
3. Turn off exclusive mode. On the Advanced tab, untick Allow applications to take exclusive control of this device. This fixes a mic that dies whenever a game or recording app is open.
4. Turn off enhancements. Driver effects can gate out quiet speech. In Windows 11, set Audio enhancements to Off on the mic's page in Settings.

Position matters too. Many USB mics pick up from the side with the logo, not the top. Speak into the wrong face and you sound distant and several decibels quieter.

Reinstall or roll back the audio driver

If the mic is missing from every list, or it stopped after an update:

1. Right-click Start and open Device Manager.
2. Expand Audio inputs and outputs and Sound, video and game controllers. A yellow triangle means the driver failed.
3. If the trouble began after an update, open the device's Properties, the Driver tab, and select Roll Back Driver.
4. Otherwise right-click it, choose Uninstall device, tick Attempt to remove the driver for this device, and restart so Windows reinstalls it.

Most recent laptops route the built-in mics through an audio processor: Intel Smart Sound Technology on Intel models, listed under System devices, or the AMD Audio CoProcessor on Ryzen models. If the Microphone Array is missing or shows an error such as Code 10, install the audio driver and that processor driver from your laptop maker's support page for your exact model. The generic versions from Windows Update can lose the built-in mics on these machines.

Windows also has a guided check: in Windows 11, Settings, System, Sound, Troubleshoot common sound problems, then Input devices. Microsoft's fix microphone problems page lists the same steps.

Laptop mics on Dell, HP and Lenovo

Dell. Waves MaxxAudio asks what you plugged in when you connect a wired headset. Pick Headphones and the headset mic is ignored. Dell's fix: open Waves MaxxAudio, go to Playback, select Advanced, tick Show pop-up dialog when device is connected, reconnect and choose Headset. If no pop-up appears, Dell says to set the Realtek and Waves audio services to Automatic. See Dell's Waves MaxxAudio article.

HP. Check the mic mute key and its light. HP's audio app (Bang & Olufsen Audio Control or HP Audio Center, depending on the model) has its own mic settings, and HP Support Assistant installs the right driver for your model.

Lenovo. F4 mutes the mic on most ThinkPads and IdeaPads, and its light stays on while muted. If the Microphone Array vanished after an update, run System Update in Lenovo Vantage.

On any laptop, the mics sit in the bezel next to the camera. A webcam cover or a sticker over that strip muffles your voice.

Headset and jack problems

The plug and the port have to match:

• A single jack with a headset icon is a combo jack. It takes a 4 pole plug, with three black bands on the metal, carrying mic and audio together.
• Desktops with separate pink and green jacks need a Y splitter for a single plug headset.
• A 4 pole headset in a headphone only port, or through a 3 pole extension cable, plays sound but loses the mic.
• A USB headset has its own sound chip and shows up as a separate input and output. Select both.
• A Bluetooth headset only uses its mic in hands-free mode, where sound turns mono and thin. For calls, a wired or USB headset sounds far better.

The headset mic test checks the earcups and the mic together. For cleaning a port, jack detection and front panel jacks, see headphone jack not working.

Teams, Zoom and Google Meet

Teams: select Settings and more, Settings, Devices, and choose your mic in Microphone. Make a test call plays your recording back, but it is not available in Teams on the web. In a meeting, open the arrow next to Mic, then More audio settings.

Zoom: Settings, Audio. Pick the mic and select Test Mic. If your level keeps sinking, untick Automatically adjust microphone volume and set it by hand. The zoom mic test checks your level before you join.

Google Meet in Chrome: select View site information at the left of the address bar and turn on Microphone. In the meeting, open More options, Settings, Audio to choose the mic. If Chrome blocks every site, open chrome://settings/content/microphone and select Sites can ask to use your microphone.

Microphone not working on a Mac

1. Open System Settings, Sound, Input, and select your mic. Speak and watch the input level, and raise Input volume if it barely moves.
2. Open System Settings, Privacy & Security, Microphone, and turn on the app. Quit and reopen it so the change applies.
3. In a call, open Control Center and check Mic Mode. Voice Isolation can cut a quiet voice along with the noise. Standard is the safe choice.
4. If a USB mic is missing, try another cable and port, then open Audio MIDI Setup in Applications, Utilities. Missing there too means macOS cannot see the mic at all.

iPhone and Android

iPhone. Remove the case and any screen protector and brush the mic openings with a soft, dry brush. Apple's test: record a Voice Memo while speaking at the bottom of the phone, then record a video while speaking at the top, switch cameras and record again. A silent recording points to that mic. If all three work, open Settings, Privacy & Security, Microphone and turn on the app. Apple's iPhone microphone guide has the same steps.

Android. Swipe down twice and make sure the Microphone tile in Quick Settings is not blocking access. Then open Settings, Apps, the app, Permissions, Microphone, and choose Allow only while using the app. A Bluetooth earbud that is still connected grabs calls and voice notes, so turn Bluetooth off to test the phone's own mic.

When it is a hardware fault

Swap one thing at a time: try the mic on another device, and another mic on this one.

• The mic fails everywhere. The mic or its cable is faulty. Headset cables usually break near the plug or at the boom hinge. Watch the meter in the mic test while you flex those spots: crackles or drops confirm it. Replace the headset or claim the warranty using the serial number on the box or headband.
• Every mic fails on this computer. Suspect the port, the driver or the board. Run the maker's diagnostics (HP PC Hardware Diagnostics, Dell SupportAssist or Lenovo Diagnostics) and keep a screenshot of the result for the claim.
• A laptop mic cuts out as you move the screen. The mic cable runs through the hinge. That is a job for the maker's service center, and often a warranty repair.

Until then, a USB headset or USB mic brings its own sound chip and works around a failed laptop mic or jack. Once your mic works, the mic quality test scores its noise, hum and clipping for calls and streaming.
