So, let’s quickly walk you through different solutions to fix the Windows Audio Device Graph Isolation High Usage problem.

  1. Scan Your PC With Antivirus

If the CPU usage for Audio Device Graph Isolation has spiked in the last few days, there’s a huge probability that your computer is infected with Virus. To confirm this, you can also check the destination folder of the process. In case, it’s located in a different folder than “C:\Windows\System32”, your PC most likely has potential malware or Virus.



In this situation, you’ll have to perform a complete Virus scan using a dedicated Antivirus program. While you can use Windows Defender to perform the scan, it’s always a good strategy to use a feature-rich paid Antivirus program. These paid applications are capable of performing detailed scans on the entire hard drive and also remove the Virus permanently. 

  1. Update Audio Drivers

If your Antivirus doesn’t fix the problem, the next step would be to update the audio drivers to the latest version. Since outdated drivers are one of the major reasons behind the high usage of Windows Audio Device Graph Isolation, installing the latest available drivers will instantly fix the problem.
Here’s how you can update audio drivers on a Windows PC.

Step 1 - Right-click the “Start” button and select “Device Manager” from the list.

Step 2 -  The “Device Manager” window will open on your screen. Here expand the “Sound, Video, and Game Controllers” option to proceed further.

Step 3 - Right-click on the installed audio driver and select “Update Driver Software”.



Step 4 - In the next dialog box, click “Search Automatically for Updated Driver Software”. Make sure that your PC is connected to an Internet connection throughout this process.

Step 5 - Now, your system will automatically look for and download the updated version of audio drivers.

Step 6 - Once the installation process completes, reboot your computer and again open “Task Manager”. This time you won’t notice a high CPU usage for the Windows Audio Device Graph Isolation process.

  1. Disable Sound Effects

Another way to control the high CPU usage of the Windows Audio Device Graph Isolation process is to disable special sound effects. This is a 100% guaranteed method, mainly because the sound engine is responsible for handling audio effects. This means when you’ll disable all sound effects on your PC, it’ll automatically reduce the high resource consumption of the process.

However, this method is only suitable for users who rarely play any special sound effects on their PC. In case you’re a gamer or work on applications like FL Studio and Premiere Pro, this method won’t be the right solution to fix the problem. In that case, you’ll have to stick with one of the previously mentioned solutions.

Follow these steps to disable all sound effects on your PC.

Step 1 - Right-click the “Speaker” icon in the right corner of the taskbar and select “Open Sound Settings”.

Step 2 - You’ll be prompted to the “Settings” window. Here click “Sound Control Panel”.

Step 3 - Now, switch to the “Playback” tab and right-click the audio output device from the list. Select “Properties” to proceed further.

Step 4 - Then, switch to the “Enhancements” tab and check the “Disable All Sound Effects” option.

Step 5 - Click “Ok” to apply your actions and repeat the same process for each playback device on your PC.

That’s it; Windows Audio Device Graph Isolation won’t consume your PC’s resources and you won’t have to deal with slow processing at all.
