Windows Audio Device Graph Isolation using high CPU

[Shanester]

Greetings,

Windows Audio Device Graph Isolation (below) has been using high CPU since the Windows October update (version 1809):

c:\Windows\System32\audiodg.exe

However, the sound still works. So far I've tried:

• Restarting
• Virus scan
• Check for new updates
• Check for new drivers
• Downloading and installing the driver again
• Running the HP Audio Check one click fix (version 1.0.1.8). It found "One or more audio service isn't running" and fixed them. However, this only fixes the problem temporarily, because if I restart, the process begins using almost 100% of my CPU again.

A YouTube video suggests removing all the audio drivers and restarting, as the drivers will get reinstalled during the restart. But I was wondering if the drivers that get installed are the HP drivers or just some generic drivers.

Thanks,

Shane.

I got a notification in HP Support Assistant saying there is a new driver available:

Conexant High-Definition (HD) Audio Driver

sp95439.exe

"This package provides the driver for the Conexant High-Definition (HD) Audio module in supported notebook models that are running a supported operating system."

I installed it, and the Windows Audio Device Graph Isolation seems to be fixed. However, these two processes are now using high CPU:

Flow 1.3.56.0
C:\Program Files\CONEXANT\Flow\Flow.exe

Using high CPU

HP Touchpoint Analytics Client 4.0.2.1439
C:\Program Files\HP\HP Touchpoint Analytics Client\TouchpointAnalyticsClient.exe

Using all my CPU

Shane.

@Shanester To begin with, Windows Audio Device Graph Isolation is a perfectly legitimate component of your Windows. It serves as the audio engine in your operating system so that third-party apps can run sound on your computer. To sound smart, we should call this digital signal processing and the fact that it's taking up CPU usage is normal if it isn't causing the computer to crash or is creating other such issues on it.

Let me know if you have any such critical issues on the device, that said, you seem to have done everything that could possibly reduce CPU usage and since the issue persists, I suggest we perform an extensive hardware test to ensure this isn't a hardware issue with the device:

• Hold the power button for at least five seconds to turn off the computer.
• Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
• On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.
• Click Extensive Test.
• Click Run once, or Loop until error.
• While the test is running, the time remaining and test result for each component display on the screen.
• If a component fails a test, write down the failure ID (24-digit code) for when you respond back to us.

Let me know how that pans out,

i sort of figured that Windows Audio Device Graph Isolation (WADGI) was a legitimate component. I also know that programs take CPU time, but WADGI was using all of my CPU. However, since installing the update (sp95439.exe), it appears to be fixed.

Although the update fixed WADGI, it cause two other components to use all of my CPU. I will try the hardware tests you suggested.

Thanks,

Shane.

@Shanester Alright, take your time and get back to us with the results.

Good luck.

It's not fixed. After rebooting, audiodg.exe is back to using all of my CPU.

I ran the Hardware Diagnostics, and the system extensive test passed. It says that it saved a log file, but I can't find it.

I'm getting desperate. I'm now using Task Manager to end the process (end task). But, of course, that doesn't fix anything.

Thanks,

Shane.

My solution to this problem was to uninstall Skype.  It was certainly involved in the issue and since uninstalling it, my x360 has shown no signs of high CPU usage from the Audio Graph Isolation process.  I now use Skype (preview) in a browser window and it works well for me.  And I don't miss those whirring fans ...

I hope that might help for you?

[Shanester]

Thanks for the suggestion. I uninstalled Skype, but the problem persists. I was also able to uninstall these apps:

Mixed Reality Portal
Microsoft Support and Recovery Assistant for Office 365

However, I couldn't uninstall other apps (below) that I don't use, because the Uninstall button is dimmed:

3D Viewer
English (United Kingdom) Local Experience Pack
Game bar
Mail and Calender
Messaging
Paint 3D
People
Xbox
Xbox Game Speech Window

Regards,

Shane.

I had this same issue, it would cause audio crackling and make my game to freeze for 5-10 seconds, completely ruining the experience. I reinstalled windows and it seems to have fixed this issue. My computer seemed to be running much hotter before the reinstall as well. If you see this process spiking I'd sugguest you wipe your OS drive clean and reinstall windows. Also, I tried avast and malware bytes, neither detected anything
