If your Razer headset microphone is not picking up your voice or audio, the issue is often caused by incorrect system or application settings. This article walks you through simple checks and adjustments to help restore proper microphone functionality on your PC.
-
Click on "Start", then type "Manage Audio Devices" in the search box. Hit "Enter".

-
Click the "Recording" tab.
-
Verify that your headset is set as the default device.

Additional Troubleshooting:
- Ensure your Razer headset is selected as the input device in-game.
- If you are using a 3rd-party chat application such as Discord or Skype, check if the “Push-To-Talk” setting is checked. If enabled, this setting will not allow the user to send audio without pressing a specific key/s.
- Ensure the microphone headset is not muted on your Razer headset’s in-line control.
