Quick check: Run the related device test and keep it open while trying these steps.
Start with a known signal
Open our microphone test and click Start microphone. Speak at your usual distance. If the level bar moves, the browser is receiving audio. Make a short clip and play it back: movement without audible playback can mean your output device or volume is the problem instead. If the meter does not move at all, work through the input checks below.
Check the physical path
Make sure the mic or headset is connected and powered. A USB microphone may need a different port; a headset may have a cable or in-line mute switch. If you use a mixer or audio interface, select that interface as the input and confirm its hardware gain or mute state. Avoid changing several settings at once: test again after each change so you know what fixed it.
Check Windows and browser permissions
In Windows 11, open Settings → System → Sound → Input and select the intended microphone. Speak into it and watch the Windows input level. If Windows does not see it, the website cannot use it either. Then check Settings → Privacy & security → Microphone, including access for desktop apps. Finally, use the icon beside this site’s address in your browser to allow microphone access. Reload the test page after changing permission.
Narrow down the remaining issue
Close a video call or recording app that may be holding the device. If Windows sees the microphone but the browser does not, try a fresh browser tab and reselect the input. If the browser test works but one calling app does not, check that app’s own input setting. A working test proves the browser got a signal; it does not measure microphone quality or fix app-specific routing.
After each change, test the device again. Change one setting at a time so you can identify what helped.
