Problems with XAudio2_6.dll can cause various issues to appear, and speaking of issues, here are some of the most common problems reported by users:

  • XAudio2_6.dll missing Windows 10, 7 – This problem can appear on any version of Windows, and older versions of Windows aren’t an exception. Most of our solutions will work with any version of Windows, so even if you don’t use Windows 10, be sure to try some of our solutions.

  • XAudio2_6.dll not found – If this file isn’t available on your system, you might be able to fix the problem simply by copying it from another PC.

Solution 1 -Reinstall DirectX

XAudio2_6.dll missing Windows 7

XAudio2_6.dll is a file related to DirectX, which is, as you probably know, one of the essentials for running almost every game on Windows 10 and other Windows operating systems. So, to solve this issue, and repair the corrupted XAudio2_6.dll file, all you need to do is to reinstall or repair your current version of DirectX, and everything should work just fine. You can download the latest version of DirectX from Microsoft’s site, for free.

If this error appears while trying to run a certain game, you can also find the DirectX setup file in the game’s installation directory. Just search for DirectX folder, and you should find the required setup file there.


Solution 2 – Update Sound Driver

Although XAudio2_6.dll is a DirectX-related file, some users also reported that updating the sound driver solved the issue. So, if you reinstalled DirectX, and you’re still facing the same error, head to the Device Manager, and check if there are any updates for your audio driver. In case you don’t know how to do that, follow these instructions:

  1. Press Windows Key + X to open Win + X menu. Choose Device Manager from the list.
    XAudio2_6.dll not found
  2. Under Sound, video and game controllers, right-click on your audio driver, and go to Update driver.
    XAudio2_6.dll Skyrim
  3. Choose Search automatically for updated driver software.
    XAudio2_6.dll missing Windows 10, 7
  4. If there are any updates available, let the wizard finish the process.

After doing that, Windows 10 will download the latest drivers for your audio device.

Although this method is quite simple, it won’t always download the latest drivers, so it might not fix your problem. If you want to completely fix the problem, it’s advised to download your drivers directly from the motherboard or sound card manufacturer.

Simply visit the manufacturer’s website, enter the model of your sound card or motherboard and download the latest audio drivers for it. This method might be a bit more complicated than the previous one, but by using it you can download the latest audio drivers for your PC.

If both these methods are ineffective, you might want to try a third-party tool that will automatically update all your drivers with a single click. TweakBit Driver Updater is such a tool, and by using it, you can update your drivers automatically in a matter of minutes.


Solution 3 -Manually Register with Microsoft Register Server

Maybe XAudio2_6.dll is present on your computer, but it’s just not registered. In most cases it (and all other .dll files) should be registered automatically, but in some cases, there could be complications. So, you can try to register this file on your own, and see if there are any improvements. Here’s exactly what you need to do:

  1. Press Windows Key + X and choose Command Prompt (Admin) or PowerShell (Admin).
    XAudio2_6.dll crash
  2. Enter the following line into the Command Prompt, and press Enter:
    • regsvr32 /u XAudio2_6.dll (this command will un-register the file)XAudio2_6.dll missing Windows 10

Solution 4 – Install the drivers in Safe Mode

According to users, problems with missing XAudio2_6.dll can occur due to your graphics card drivers. Some users reported that this issue occurs while installing AMD drivers, and in order to fix the issue, it’s required that you enter Safe Mode and try to install the drivers from there.

In case you’re not familiar, Safe Mode is a special segment of Windows that runs with default drivers and applications, so it’s perfect for troubleshooting. To enter Safe Mode, do the following:

  1. Press Windows Key + I to open the Settings app.
  2. Go to System & Security section.
    XAudio2_6.dll Skyrim
  3. Choose Recovery from the left pane. In the right pane, in Advanced startup section click Restart now.
    XAudio2_6.dll crash
  4. Choose Troubleshoot > Advanced options > Startup Settings. Click the Restart button.
  5. When your system restarts you’ll be presented with a list of options. Select Safe Mode with Networking by pressing the corresponding key.

Once you enter Safe Mode, try to install the AMD driver once again. If you manage to install it successfully the issue should be completely resolved.


Solution 5 – Clean your registry

Few users reported that they managed to fix the problem with XAudio2_6.dll simply by cleaning their registry. In some cases, your registry entries can become corrupted, and that can cause this and many other errors to appear.

To fix the problem, some users recommend cleaning your registry. The simplest way to do that is to use a registry cleaner software. We covered many registry cleaners in the past, and if you’re looking for a good software to clean your registry, we recommend you to try Advanced SystemCare.


Solution 6 – Remove overclock settings

Sometimes the problem with XAudio2_6.dll error can occur while trying to run certain games. According to users, the issue was caused by their overclock settings, and after removing the overclock settings, the problem was completely resolved.

If your system is overclocked, lower your overclock settings or disable them completely and check if that solves the problem. This isn’t the most reliable solution, but it might work for you, so be sure to try it out.


Solution 7 – Install the missing updates

If the problem with XAudio2_6.dll appears, the issue might be missing Windows updates. Sometimes if you don’t have the latest updates installed, you might encounter certain issues. However, you can easily solve these issues by installing the missing updates.

Windows 10 usually installs the missing updates automatically, but sometimes you might skip an update or two due to certain issues. However, you can always check for updates manually by doing the following:

  1. Open the Settings app and go to the Update & Security section.
  2. Now click Check for updates button.
    XAudio2_6.dll not found

If any updates are available, they will be downloaded in the background and installed as soon as you restart your PC. Once your system is up to date, check if the problem is still there.


Solution 8 – Manually copy the missing files

In some cases, you might be able to fix the problem with missing XAudio2_6.dll simply by copying it from another PC. To do that, switch to a different PC and search for the missing file. If you find it, copy it to the other PC and check if that helps.

The file should be located in Windows/System32 and Windows/SysWow64 directories, so be sure to copy it there on your PC. Many websites will also offer you to download this file, but most of these websites aren’t reliable, so it’s always better to copy this file from another PC.
