Hello Prosper Popplewell,
Welcome to Microsoft Community.
In fact, you should be very close to the cause of the problem. Because from your description, it seems that your laptop does not recognize the microphone of your headphone device at all.
Solving the microphone problem can be a bit tricky, but let's try it step by step.
1. Update the audio driver:
This is my top recommendation for you to try. Outdated or damaged audio drivers can cause problems. Make sure your audio driver is updated to the latest version. Find "Sound, Video and Game Controllers" in the Device Manager, then right click on the audio driver and select Update Driver.
2. Uninstall and reinstall the audio driver:
After right-clicking on the audio driver, you will also see the option to "Delete device", click on it to uninstall, and then restart the device. During the reboot, the audio driver is reinstalled.
3. Run the Windows Troubleshooting program:
Windows has a built-in troubleshooting program that can help identify and fix common problems with hardware and devices.
Go to "Settings" -- "Update and Security" --"Troubleshooting".
Under "Find and Resolve Other Issues," select "Hardware and Devices," and then run the troubleshooting program.
4. Check the Razer Synapse software:
If your headset comes with dedicated software, such as Razer Synapse, check for any Settings that might affect your microphone.
5. Check for Windows updates:
Make sure your Windows operating system is up to date, as updates can often fix hardware-related issues.
6. Restart the Windows Audio service:
Sometimes restarting the Windows Audio service can help re-identify to the microphone.
- Press Win + R, type services.msc, then press Enter.
- Scroll down to find "Windows Audio."
- Right-click Windows Audio and select Restart.
7. Check the default communication device:
Windows allows you to set the default communication device separately from the default audio playback device.
- Right-click the volume icon in the system tray and select "Open Sound Settings".
- Scroll down to the Input section and click Device Properties.
- Under Use this device for sound input, select Communication.
If none of the above steps work, it may be worth contacting Razer's customer support for further help, as there may be specific headphone compatibility or driver issues.
