If you’re using a Secure or Locked-down Browser (often required for proctored tests) and your microphone isn’t being detected, it’s usually due to restricted permissions or system-level blocking. This can prevent the system from capturing your audio, which may lead to interruptions, inability to communicate, or even disqualification from the test. In this article, you’ll learn the common reasons this happens and how to resolve it.

​
✅ Common Causes and Fixes

What Might Be WrongWhat You Can Do
Secure browser blocks device accessRestart the secure browser and ensure all permissions are granted when prompted.
Mic access not allowed in system settingsGo to system settings and enable mic access for all apps.
Another app is locking the micClose other apps like Zoom, Teams, or Skype that might be using the mic.
External mic not connected properlyReconnect the USB or audio jack. Try a different port if needed.
Mic disabled in BIOS or device managerCheck system BIOS (advanced) or use Device Manager to enable it.
Antivirus or security software is blocking micTemporarily allow mic access or ask IT to whitelist the secure browser.

​
🔧 Final Check: Allow Microphone at OS Level

Make sure the operating system allows microphone access for all applications:

​
Windows:

  • Go to: Settings > Privacy & Security > Microphone
  • Enable microphone access for all apps (secure browsers may not appear by name)

​
macOS:

  • Go to: System Settings > Privacy & Security > Microphone
  • Ensure microphone access is turned ON system-wide

​
Secure Browsers Tip:

  • If you denied mic permission when prompted at launch, exit and relaunch the secure browser—it won’t ask again unless restarted.
  • Run a Mic Test before launching the secure browser to verify it’s functioning.
  • Use the internal mic if the external one fails
  • Reboot your device before launching the secure browser again
