Open up the Sound properties dialog by right-clicking the speaker icon in your Notification area and then clicking “Sound.” You can also open up your Control Panel and run the Sound applet there. You can also do it right in Windows for devices that support it. You can certainly try whatever software your hardware manufacturer supplies and see if you can disable some of the advanced audio effects. The good news is that it’s likely easy to resolve since part of the reason for isolating this type of processing is giving you an easy way to turn it off. These numbers may spike when audio effects are being applied, but not much and they should return to the baseline quickly. If you see “Windows Audio Device Graph Isolation” routinely using more of any of these three resources, then you may have a problem.
Under normal conditions, you should see “Windows Audio Device Graph Isolation” using 0% of your CPU, minimal memory, and no disk activity. Some people have trouble with enhancements causing significantly higher use of system resources, consuming your CPU or memory or even thrashing your hard drive. Unfortunately, poorly written audio enhancement drivers can cause more than just the occasional crash. Of course, if you don’t have “Windows Audio Device Graph Isolation” running on your system, you won’t have much need to troubleshoot it! Why Does It Sometimes Consume So Many System Resources? Here’s a look at the service used by a Creative SoundBlaster Recon3D. You should also note that with some audio hardware, manufacturers may actually replace the “Windows Audio Device Graph Isolation” with their own digital signal processing service. For whatever reason, audio hardware manufacturers very often don’t give you that option themselves. This type of isolation also ensures that Windows always provides you a way to turn off audio enhancements in the OS, regardless of what type of hardware you’re using. By isolating the digital signal processing–the part more likely to experience a crash–to a separate service, crashes are more contained. Windows Audio is so deeply hooked into Windows that a crash is often likely to take down the whole system rather than just your sound. This, in turn, leads to better stability. Isolating the services like this allows developers of hardware audio products include their own audio enhancement service without having to replace the Windows Audio service itself. “Windows Audio Device Graph Isolation” is separated from the standard Windows Audio service. It handles digital signal processing, including the advanced audio enhancement effects provided by Windows.
The process serves as the primary audio engine in Windows 10. Sporting an awesome-sounding name that doesn’t really tell you anything, “Windows Audio Device Graph Isolation” is an official part of Windows. What Is the “Windows Audio Device Graph Isolation” Process?
