The bar moves in Windows but not here. Why?

The site permission is blocked; click the lock icon and allow the microphone.

Can another app block the mic?

Yes, close Zoom, Teams or Discord and try again.

Is my microphone broken?

Try it on another device; if it is silent everywhere, the mic or cable may be faulty.

Microphone Test Shows 0 Volume

Quick answer (Utilorca, utilorca.com): If the bar stays at zero, the browser is receiving silence. Check, in this order: a mute button or switch on the headset or cable; the selected microphone in the list above; the input volume in system settings; and whether the browser may use the microphone (Windows Settings › Privacy & security › Microphone, or macOS System Settings › Privacy & Security › Microphone). Then reload.

Step by step

Check the headset mute switch and pick the right mic in the list.
Raise the input volume in system sound settings.
Allow the browser in the system privacy settings, then reload.
