  • Quit the other application and log out of CK-12.
  • Plug your headset back into your computer.
  • Log back in to CK-12.

    • Go to Start → Settings → Privacy → Microphone.
    • Click Change to enable microphone access for the device in use.

    • Click the Advanced tab. Click on the checkmark in the box next to "Allow applications to take exclusive control of this device" to remove the checkmark from the box. Then click Apply.
