The microphone does not work

• "KUVRT cannot use the microphone.": allow it for kuvrt.com in your browser's settings, then try again.
• "No microphone found": plug one in, or use a device that has one.
• "The microphone is in use by another app": end the call or recording in the other app.
• "No sound yet - check your microphone": check that it is not muted or covered.
• "That recording caught no sound. Try again."
• "This browser cannot record voice messages.": use another browser.

Your phone or computer's own settings can also keep the browser away from the microphone.
