What is audio device graph isolation in Windows?

How to fix high CPU usage by isolating Windows audio device graphs.

Slow computer performance can be dangerous, as high usage can eventually damage your processor.

Windows audio device graph isolation is one of the applications that can consume the CPU. It's easy to find out by checking the Task Manager and identifying the process. In general, isolation of Windows audio device graphs is part of the Windows sound engine; otherwise, it is called digital signal processing. This utility allows third-party applications to run sound on the computer, as well as apply special effects to the sound (reverberation, bass boost or echo simulation, etc.). As a result, you don't need to change Windows Audio itself to add any additional sound effects.

Sometimes, you can hear that Windows Audio Device Graph Isolation is a malicious application, and its presence can provoke a bunch of problems on the computer. In fact, it is not; this process is part of your Windows operating system. However, there is a possibility that this process could be disguised as a virus. In this case, there is a high probability that damage to your computer will still be done.

Where is the audiodg.exe file situated?

Whether it is a virus or not, you can check the location of the process when Windows audio device graph isolation is running.

Hover over the taskbar, and right-click on an empty spot.

Now, select from the Task Manager list. Now, find the Windows Audio Device Graph Isolation and right-click on it. Then select Open File Location and check the location of the file. It should be located at:


If your file is not in this folder, most likely, you are dealing with a virus.

In this case, you need to get rid of the impending threat.

Everything in order!

What if audio graph isolation leads to high CPU

Some great and effective methods can help you reduce high CPU usage. One of them will really help you. Let's get started!

Method 1. Turn off the sound effects

You can disable sound effects to reduce high CPU usage. If this is not an option for you and you need sound effects, then it is better to start solving the problem with a different method.

If everything suits you, then go to the start menu and select Control Panel.

Next, you need to select the view mode - Large icons.

Select the "Sound" section, in the new window, and then right-click on Speakers. Select Properties from the list. In the next window, go to the Improvements tab and select the Disable All Sound Effects checkbox. Confirm that you agree with the changes, and then click OK. If you still have playback devices, follow the same steps and restart your computer at the end.

Method 2. Change your audio drivers

Drivers for playback devices should always be updated. You can do this by downloading and installing updates on the official website or manually through the Device Manager.

The last update option looks like this:

Open the Device Manager and then go to the Sound, video, and game controllers section. Select the audio driver with the right mouse and click "Update Driver." In the new window, click on Search automatically for updated driver software. If there are active updates, they will be downloaded automatically.

After that, you must definitely restart your computer for all changes to take effect.

Method 3. Do you have a Skype?

Users regularly report that the problem with isolating Windows audio device graphs is somehow related to Skype, and reinstalling it solves the problem.

You can also uninstall the program through the Control Panel. Here, you need to select the Programs and Features section and right-click on the Skype icon. Then click on Delete and confirm your decision.

You can reinstall Skype from the official website by selecting the required version of the application and following the Installer's recommendations.

Remember that reinstalling the application will result in the loss of the accumulated files; therefore, back up this data if you need it in the future.
