13 Simple Fixes for Lethal Company Microphone Audio Issue on PC

A microphone connected to the PC while playing online multiplayer video games can be useful enough to talk with teammates or friends. But that might not be necessary for each multiplayer title due to the nature of the gameplay. However, Lethal Company players can connect a microphone to get voice communications while coordinating with teams for better efficiency. It’s quite unfortunate that recently several players have been experiencing the Lethal Company Microphone Audio Issue on the PC.

Well, the in-game voice chat feature is one of the important parts of the online multiplayer titles to play with friends or teammates without any issues. However, some players may go through microphone-related issues in multiple scenarios that we can’t deny. Several reports claim that the microphone audio not coming out is troubling many players. Now, if you’re also one of the victims of such an issue, don’t worry. As this is a common problem, affected players can get a workaround for it.

1. Reboot the PC

It’s highly recommended to reboot the PC manually before following other troubleshooting methods until the problem has been fixed. Sometimes a normal system reboot can fix multiple issues with the glitches or program data caches. To do that:

Open the Start menu.
Click on the Power icon > Click on Restart.

Once the system reboots, check for the issue again.

2. Run Lethal Company as an Administrator

You should run the game executable application as an administrator to avoid user account control regarding privilege issues. The chances are high that your game application is getting blocked by the system admin permissions. To do this:

Right-click on the LethalCompany.exe app on your PC.
Now, select Properties > Click on the Compatibility tab.

Enable the Run this program as an administrator checkbox.
Click on Apply and select OK to save changes.

3. Update Lethal Company

Sometimes an outdated game patch version can trouble you a lot with the startup or voice chat in the multiplayer sessions. It’s recommended to check for the game updates manually by following the steps below.

Open Steam > Go to Game Library.
Right-click on Lethal Company.
Select Properties > Click on Updates.
Head over to Automatic Updates.
Select Only update this game when I launch it.
It’ll automatically install updates whenever available.

6. Deactivate Firewall and Antivirus

It’s also worth recommending to disable Firewall on the PC. Otherwise, the aggressive Windows Firewall prevention may block ongoing connections which can trigger issues with the server syncing or voice chat. To do that:

Click on the Start Menu > Type and search firewall.
Open Windows Defender Firewall from the search result.
Now, click Turn Windows Defender Firewall on or off from the left pane.

Select the Turn off Windows Defender Firewall (not recommended) option.

Press the Win+I keys to open Windows Settings.
Click on Update & Security > Click on Windows Security from the left pane.
Now, click on the Open Windows Security button.
Go to Virus & Threat Protection > Click on Manage Settings.

Next, you’ll need to Turn Off the Real-time protection toggle.
If prompted, click on Yes to proceed further.

7. Install Microsoft Visual C++ Redistributables

Another thing you can do is to install Microsoft Visual C++ Redistributables on your Windows by following the steps below. The C++ runtime libraries are always required for running resource-heavy programs and video games smoothly which are developed by Visual Studio. It’s a useful component for Windows programs, especially AAA titles. So, if you’re running an outdated VCRedist version or don’t have any version then you should follow this method.

Navigate to the Visual C++ Redistributables download page.
Download and Install the latest version on the PC.
Once done, reboot the PC to apply changes.

8. Use Push To Talk

Some players have mentioned that PTT (Push To Talk) is one of the key factors in microphone not working issues for multiplayer titles. It seems that using push-to-talk in the game menu might help in fixing the microphone audio issue on the PC.

Open Steam > Go to Library.
Launch Lethal Company > Head over to the in-game Settings (options) menu.
Ensure to locate the Voice Communication Settings.
Enable the Push-to-Talk (PTT) feature.
Now, assign a key/button that will easily turn on & off the microphone during gameplay sessions.

Press the Win+I keys to open Windows Settings.
Go to the Privacy & Security section.
Click on Microphone under App Permissions.
Enable the Let desktop apps to access your microphone toggle.
Finally, check for the voice chat not working issue.

10. Set the Correct Audio Input Device

We’ll also suggest our readers check the Audio Input Device manually on the PC by following the steps below to ensure the input audio device is correctly selected. Without selecting the input device, your Windows system sometimes might not be able to detect the actual device or microphone.

Right-click on the sound icon on your taskbar.
Click on Open Sound settings.
Now, choose your Input device that’s connected under the Input section.

Make sure to test out the changes with the Master volume.

11. Check the Windows Sound Settings

Several players may experience sound settings-related issues while playing video games and communicating with other players via voice chat. It looks like the headset microphone is not correctly configured to the default input device which results in communicating issues during the gameplay sessions. So, you can follow the steps below to manually set your headset mic to the default mode.

On the bottom right side of the taskbar, right-click on the Volume icon.
Click on Sounds > Select the Recording tab.
Right-click on the headphone (mic) device that you’re currently using.

Next, select Set as Default Device > Choose Set as Default Communication Device.
Then right-click on your default microphone > Select Properties.
Go to the Levels tab > Drag the slider of the Microphone to increase the volume level.
Once done, click on OK to save the changes.

12. Try Checking the Microphone on a Different Device

In case, you’re still experiencing the microphone not working issue on your Lethal Company then make sure to cross-check the microphone on a different device. The chances are high that somehow your microphone has some issues and that’s why you’re facing the voice chat conflicts. So, it’s always a better idea to check for the same on another device.

13. Use Another Microphone

Last but not least, try using another microphone on your PC to ensure whether you’re still encountering the voice chat not working issue or not. In case, your existing microphone has some issues then you’ll anyway have to get a new one to check for the issue. Otherwise, you can get your existing microphone repaired if it’s possible.
