Reporting a problem with the test

It helps a lot if you include:

• Your device and operating system, for example “MacBook Air, macOS 15” or “Pixel 8, Android 15”.
• Your browser and its version.
• The microphone or headset you were testing.
• What you expected to happen, and what happened instead, including any message the tool showed.

Before you write

If your microphone isn’t being picked up, the troubleshooting guides solve most cases in a couple of minutes:

• Mic not working
• Microphone permission blocked
• Mic too quiet
