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

​
🔧 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
