There have also been some instances over the years where bad BIOS versions have caused sound issues. So go ahead and update your BIOS to the latest version. Once you have done that, keep working through the steps in this guide until you solve the problem.

Make Sure Your GPU Drivers Are Up to Date

  • Update the driver if a newer version is available.
  • Restart your PC after updating.

Configure Eden’s Audio Engine

  • Open Eden.
  • Go to Emulation > Settings > Audio.
  • Try switching the Output Engine between Cubeb, SDL, or any other available backend.
  • Save and test your game afterwards.

Clean Installation of Your Graphics Drivers Using Display Driver Uninstaller (DDU)

If it has been a while since you last clean installed your graphics drivers, this is a really good idea.

  • Download Display Driver Uninstaller (DDU) from its official site.
  • Download the latest stable driver for your GPU from Nvidia's or AMD’s official website.
  • Disconnect your computer from the internet to prevent automatic driver updates during the process.
  • Run DDU and follow its instructions to fully remove your current GPU drivers.
  • Restart your system once the removal process completes.
  • Install the freshly downloaded GPU driver.
  • Restart your system and reconnect to the internet.
  • Launch Battlefield 6 to check if the issue has been fixed.

Update Eden Emulator to the Latest Version

  • Download the most recent Eden release from the official source.
  • Replace (or update) your old installation.
  • Launch Eden and verify the version number.

Adjust CPU & Graphics Settings

  • Go to Emulation > Settings.
  • Under CPU:
  • Enable Multicore CPU Emulation.
  • Set CPU accuracy or mode to Auto (or the recommended default).
  • Open the Graphics section:
  • Use Vulkan if available: usually smoother than OpenGL. (Most games)
  • Set Resolution Scale to 1x during troubleshooting.
  • Pick your dedicated GPU, not the integrated one.
  • Disable VSync under Advanced settings.
  • Enable the remaining recommended performance options.
  • Choose High accuracy for strong GPUs or Normal for weaker ones.

Switch Your Game Files to NSP Format

  • Convert or replace XCI game files with NSP versions.
  • NSP formats tend to load more reliably and avoid audio hiccups in Eden.

Refresh Your Product Keys After Updating Firmware

  • Open Eden > File > Open Eden Directory.
  • Go into the keys folder.
  • Remove old prod.keys.
  • Place the updated key files into the folder.
  • Restart Eden.
