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.
4. Update Sound Driver
- Press Windows Key + X, and choose Device Manager from the list.
- Under Sound, video and game controllers, right-click on your audio driver, and go to Update driver.
- Choose Search automatically for updated driver software.
- 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 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.
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.
Driverfix is such a tool, and by using it, you can update your drivers automatically in a matter of minutes.
5. Install the drivers in Safe Mode

- Go to System & Security section.
- Choose Recovery from the left pane.
- In the right pane, in the Advanced startup section, click Restart now.
- Choose Troubleshoot > Advanced options > Startup Settings. Click the Restart button.
- 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.
According to users, problems with missing XAudio2_6.dll can occur due to your graphics card drivers.
