The Windows Audio Device Graph Isolation is the executable file that helps users get a better audio quality on their PCs. Aside from enhancing audio users also get to have different audio effects because of this executable file. This audio engine file is located in the C:\Windows\System32 folder by default in Windows 10 and all other older versions of Windows.
If your PC is infected with a malware or if the connected audio driver has become corrupted or damaged, this audio file might start using high CPU or memory. To fix it, try out the solutions laid out below.
Option #1 – Try to uninstall and reinstall Skype
You have to uninstall the Skype app completely as well as the desktop software to fix the problem. After you do, restart your PC and install it once again and check if the problem’s fixed.
Option #2 – Update your Audio driver
You might have to install the proper audio driver or update your existing one to the latest version if you had started getting the high CPU usage problem of Audiodg.exe when you recently installed a new sound device. To update your Audio driver, refer to these steps:

  • Open the Run dialog box by tapping Win + R on your keyboard.
  • Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.

  • After that, a list of device drivers will be displayed. Look for your audio driver and if you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software”. And if you find any “Unknown device”, you need to update it as well.

  • Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.

Option #3 – Try to disable all Sound effects
You can also try to disable all of your sound effects if you are currently using any and check if it fixes your high CPU usage issue or not. Refer to the steps below to disable Audio enhancements.

  • In the system tray, right click on the Audio icon and then select Playback devices.
  • After that, the box for Sound Properties will be opened. In there, the speakers will have a green checkmark.
  • Select the check mark and click on the Properties button.
  • Once you’ve opened the Speaker Properties window, go to the Enhancements tab and check the checkbox for “Disable all sound effects” and then save the changes you’ve made.

Option #4 – Try to run the Audio Troubleshooter

Option #5 – Scan your computer using an antivirus program
