Resolving Helldivers 2 Audio Crackling and Sound Problem Solutions

Since its release over a year ago, Helldivers 2 has received a mixed response from players, particularly regarding its PC version, which, while generally well-received, still grapples with notable technical issues. Among these, audio problems, such as unwanted crackling noises, have caused frustration for many users, compounded by the absence of advanced upscaling options like DLSS within the game.

To assist you in resolving these audio challenges, I’ve compiled a series of effective solutions aimed at eliminating the crackling sound experienced by some players in Helldivers 2.

Bluethooth Connectivity and Audio Issues

If you are experiencing crackling audio while using a Bluetooth audio device while playing Helldivers 2, the following adjustments may help resolve the issue. It may be beneficial to try both solutions outlined below to determine which one is effective for your setup.

Disable Hands-Free Telephony

This solution, recommended by Arrowhead Game Studios, has been successful for many players:

Access Windows Settings and navigate to the Bluetooth & devices section.
Your Bluetooth headset should be listed; right-click on it and select Properties.
In the Services tab, uncheck the option for Hands-free telephony.

Now, relaunch Helldivers 2 to check if the crackling sound persists. If it does, proceed with the next recommendation.

Disable Bluetooth Audio Gateway Service

Another recommendation from Arrowhead Game Studios that has proven beneficial for many players on platforms like Steam and Reddit is to disable the Bluetooth Audio Gateway Service:

Type “Services” in the Windows Search bar and open the first result.
Scroll through the list until you locate Bluetooth Audio Gateway.
Right-click the service and select Stop.
Then right-click again, choosing Properties.
Under the Startup type dropdown menu, select Disabled.

Further Audio Troubleshooting Tips

In addition to the aforementioned Bluetooth suggestions, consider these further strategies to improve your audio experience in Helldivers 2.

Set Correct Communication Devices

Ensure that the game is utilizing the correct audio input and output settings in Windows. Follow these simple steps:

Minimize Helldivers 2 after launching it.
Right-click the audio icon on the taskbar and select Audio Mixer.
Locate Helldivers 2 within the Apps section.
Expand the options and confirm that the appropriate devices are selected for both input and output.
For example, if you are utilizing NVIDIA Broadcast for your microphone, make sure to select this instead of the typical microphone option.

Be mindful that sometimes this may default to an incorrect setting.

Important Tip: If you do not engage in in-game voice chat, select an input device that isn’t your headset if your headset has a dedicated mic. Surprisingly, this change has resolved audio issues for many players.

Disable Spatial Sound Features

Another potential fix involves disabling spatial sound, which might help rectify audio problems. Here’s how:

Navigate to Windows Settings, then to System, and select Audio.
Identify and click on your output device, then scroll down to the Advanced Settings section to toggle Spatial Audio to Off.

Verify Game Files Integrity

It’s possible that issues originated during the download or installation process, leading to corrupted or missing files. To ensure this isn’t the case, you can verify the integrity of your game files in Steam:

Open the Steam client and head to your Library.
Right-click on Helldivers 2 and select Properties.
In the Installed Files tab, click Verify the integrity of game files.

Update Your Audio Device Drivers

If your audio device includes its dedicated software, consider checking for firmware or driver updates. This step is crucial for optimal performance.

Implementing these suggestions should significantly enhance your audio experience in Helldivers 2 and ideally resolve any crackling noises. It’s worth noting that Arrowhead Game Studios is aware of ongoing issues, especially concerning Bluetooth headsets, and actively working on improvements.
