Quick Answer
When a mic stops working, the fastest path is to separate hardware, browser permission, app selection, and input-level problems. Start with a browser mic test, then work outward.
Step-by-Step
- Open the Microphone Test and allow browser permission when prompted.
- Confirm the correct input device is selected in your browser, meeting app, and operating system.
- Check whether the mic is muted physically, muted in software, or set to very low input volume.
- Try another browser or app to see whether the problem is browser-specific.
- If the mic is still missing, unplug and reconnect it or restart the device.
Recommended Workflow
Open the most relevant calculator or utility first, enter a realistic starting point, then use the supporting tools to check assumptions, clean inputs, or prepare the final output.
FAQs
Why does the mic work in one app but not another?
The app may be using a different input device or may not have microphone permission.
Should I test in the browser first?
Yes. A browser microphone test quickly shows whether the computer and browser can detect audio input.
