The microphone may not be selected as the default recording device. Set the device to the default device and then check that it works. If you’re still having a problem, try the steps below:

• We recommend navigating to your Settings > Privacy > Microphone and making sure that everything is enabled for use with the mic. 
• Access your Sound Menu to confirm that the Gaming Mic is recognized on the list.
  • Access your Sound Menu by right clicking on your Speakers/Volume icon and selecting “Sounds” or typing “Sounds” into your Windows Search box. 
• Click the Recording tab and right click on your Gaming Mic to select Set as “Default Device”. 
• If there are other Ready devices, please disconnect the device or disable the microphone by right clicking on the device and then selecting Disable.
• Other devices like webcams or headsets could interfere with your Gaming Mic.
• Disconnect your Gaming Mic, wait three seconds, then reconnect your Gaming Mic to finalize the changes.
• On the Recording tab double click on the Gaming Mic to open the Properties Menu.
• Select the Levels tab then select an appropriate volume level (start at midway point of the slider & adjust from there) and make sure that the speaker icon is not muted.
• The main input/gain control can be adjusted on your microphone Gain knob (if available).
