❓ Frequently Asked Questions

Why did my PC microphone stop working after a Windows update?

Windows updates often reset privacy settings or install generic drivers that may not work optimally. Check privacy settings first, then update to manufacturer-specific drivers.

How do I fix "microphone access is turned off for this device" error?

Go to Settings → Privacy & security → Microphone, and turn on "Microphone access for this device" and "Let apps access your microphone." You may need administrator privileges.

Why does my USB microphone work on other computers but not my PC?

This indicates a PC-specific issue such as driver conflicts, USB port problems, or Windows privacy settings. Try different USB ports and check Device Manager for conflicts.
