How to narrow the problem down in 30 seconds

Microphone problems feel mysterious because there are so many places a signal can be blocked, but you can eliminate most of them with a single test.

Press the test button above and speak. If the meter moves, everything from the microphone capsule to your operating system to your browser is working correctly. That eliminates hardware, cables, drivers and OS permissions in one step, and means the fault is inside whichever application is failing — so go straight to the Discord, Zoom or Chrome guide.

If the meter does not move, try every device in the dropdown before concluding anything. Computers routinely default to a disconnected headset or a monitor's built-in microphone. If none of them react, the problem sits below the browser and you should open the guide for your operating system.

If the meter moves but nobody can hear you clearly, this is a quality problem rather than a connection problem. The quiet microphone guide covers levels and gain, and the echo guide covers feedback and room reverberation.

The three most common causes, in order

CauseTypical signGuide
OS privacy setting blocking appsMic works in system settings but is silent in every appWindows 11 · macOS
Wrong input device selectedWorked before a headset was plugged or unpluggedWindows 10
App-level sensitivity or permissionWorks everywhere except one programDiscord · Zoom

Before any of this, check for a physical mute switch on your headset cable, on the microphone body, or on a laptop function key. It is the fastest thing to rule out and it accounts for a real share of cases.

Microphone troubleshooting FAQ

Which guide should I start with?

Run the microphone test on this page first. If the meter moves, your hardware works and the problem is inside one specific application — go to the Discord or Zoom guide. If nothing moves, start with the guide for your operating system.

Do I need to install anything?

No. Every test on this site runs in your browser, and every fix uses settings that already exist on your computer.

Why does my mic work on this page but not in my app?

Browser permission and application permission are separate systems, and every app keeps its own input device selection. A working test here proves the hardware, drivers and operating system are fine, which narrows the problem to that one app's settings.

Is my audio being recorded?

No. The test uses your browser's built-in microphone API and analyses the signal locally with the Web Audio API. Nothing is uploaded and nothing is stored on a server.

My mic works but I sound terrible — is that covered?

Yes. The quiet microphone guide covers levels and gain staging, and the echo guide covers feedback and room reverberation, which are the two most common quality complaints.

Everything checks out?

Run the rest of the device tests — webcam, speakers, keyboard, mouse and screen.
