Frequently Asked Questions

Why did my mic suddenly stop working?

Common triggers include updates, accidental disconnections, or software conflicts. Check your settings or try other devices.

How do I know if my mic is broken?

Test with multiple devices to see if the issue persists. If it works elsewhere, the problem is likely software-related.

Can updates break my microphone?

Yes, particularly after operating system or app updates that change permissions or settings. Always check after updates.

Why does it work in some apps but not others?

This can be due to per-app permissions that restrict microphone access. Always check individual app settings.

Should I buy a new microphone?

Not yet—most issues (about 90%) are software-related and can be resolved without hardware replacement.

How do I reset all mic permissions?

Reset permissions through your browser settings for web apps and check OS-level privacy settings for installed applications.

Works here but not in [app]?

Check the app-specific settings to ensure it has permission to access your microphone and that the correct microphone is selected.
