Microphone not working on ChromeOS
If your microphone isn't working on ChromeOS, it's almost always one of three things: the wrong input device is selected, the mic is muted, or an app doesn't have permission. Work through the steps below, then confirm with the live test.

Step-by-step fix
- Open Settings → Audio (and the 🔒 site permission in Chrome) and pick the correct microphone as the default input.
- Make sure it isn't muted — in software and on any hardware mute switch.
- Grant microphone permission to your browser and app in Settings → Security and Privacy → Microphone.
- Run the CheckMyMic microphone test and speak — watch for the live meter and a green "your mic works" verdict.
- Still nothing? Update or reinstall your audio driver, then restart ChromeOS.
Frequently asked questions
Why is my mic detected but silent on ChromeOS?
Usually the input level is at zero or the wrong device is selected. Raise the input volume in Settings → Audio (and the 🔒 site permission in Chrome) and confirm the active device matches the mic you're speaking into.
How do I know which microphone ChromeOS is using?
Open the CheckMyMic mic test, press Start, and use the device dropdown — the mic that moves the meter when you speak is the active one.
