  1. Ensure the microphone is attached properly
  2. Rule out the hardware failure
  3. Set your headset as the default device
  4. Update the audio driver
  5. Run the sound troubleshooter

Fix 1. Ensure the microphone is attached properly

Since the Blackshark V2 headset comes with a detachable mic, it’s important to connect your microphone properly and bend it until it’s parallel to your mouth.

Fix 2. Rule out the hardware failure

If your mic is still not working, you can rule out any headset hardware issues by connecting your Razer BlackShark V2 to a different audio source. If the mic works just fine with other devices, you can move on to the next fix.

But if it’s still not working whatsoever when connected to another audio source, you may want to contact Razer Support to have your headset replaced or repaired.

Fix 3. Set your headset as the default device

It’s possible that your Razer BlackShark V2 is not set as the default device, thus causing the mic not working issue. To move on to other fixes, you should take a look at this setting:

1) Right-click the volume button in the notification area, and click Sounds.

2) Go to the Recording tab, and make sure your Razer Blackshark V2 is set as the default input device. If not, you can right-click your headset, and select Set Default.

3) Then you can right-click your headset and select the Properties > Levels tab. Make sure the volume is set at an appropriate level.

4) Click OK to save the changes.

Once you have set your Razer BlackShark V2 as the default input device, you can test your microphone. If it’s still not working, you can try the next fix.

Fix 4. Update the audio driver

If the audio driver on your PC is outdated or gets corrupted, you may enocunter the Razer BlackShark V2 mic not working issue. To keep your gaming headset always in its tip-top condition, you can try updating the audio driver.

There are two ways for you to update an audio driver:

Option 1 – Manually – The manual process requires you to visit the manufacturer’s website to download the latest driver and install them manually, which is time-consuming, technical, and risky. We don’t recommend it unless you have excellent computer knowledge.

Option 2 – Automatically – Updating your driver automatically, on the other hand, is very easy. Simply install and run Driver Easy, and it will automatically find all the devices on your PC that need new drivers, and install them for you. Here’s how to use it.

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will scan your computer and detect any problem drivers.

3) Click the Update button next to your sound device or your Razer BlackShark V2 to download the latest and correct driver.

Or you can also click the Update All button at the bottom right to automatically update all outdated or missing drivers on your computer. (This requires the Pro version — you will have full tech support and a 30-day money-back guarantee.)

4) Restart your computer for it to take effect.

The Pro version of Driver Easy comes with full technical support.
If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com.

Once the audio driver is updated sucessfully, you can test your microphone and see if the Razer BlackShark V2 mic issue has been resolved.

Fix 5. Run the sound troubleshooter

If the workarounds above failed to solve your Razer BlackShark V2 mic not working, you can try running the built-in audio troubleshooter and follow its recommendations.

1) Right-click the volume button in the notification area, and select Troubleshoot sound problems.

2) Follow the instructions given in the popped-up Help window.

3) You may need to restart your computer for the changes to take effect.

1) On your keyboard, press the Windows logo key and R at the same time.

2) Type appwiz.cpl in the box and press Enter.

3) Right-click Razer Synapse and select Uninstall.

4) Download the latest software from the Razer official website, and complete the installation.

Fix 7. Update the firmware

1) Ensure the dongle and headset are plugged into the PC directly, bypass any USB hubs or extensions.
