Fix High CPU Usage by audiodg.exe in Windows 10

High CPU usage is one of the causes behind the slowing down of Windows systems. The cause behind high CPU usage could either be insufficient RAM or a process utilizing too much of system resources. One such process which causes high CPU usage is audiodg.exe.

High CPU Usage by audiodg.exe

The process audiodg.exe is for Windows Audio Device Graph Isolation. This process allows the sound driver to run independently of the user profile and thus we cannot kill the process directly.

High Cpu Usage Due To Windows Audio Device Graph Isolation

The audiodg.exe process doesn’t shoot the disk utilization to 100% alone but could do so when combined with other system processes, yet it utilizes a lot of system resources.

Cause

The causes for high CPU Usage by audiodg.exe are as follows:

1] Certain audio effects when enabled push this process.

2] The sound driver might not be updated.

3] Drivers needed by gaming devices might not be updated.

When the drivers are not up to date, the concerned utilities push the audiodg.exe process harder to make up for the same.

We could try the following steps sequentially to resolve the problem:

1] Update the driver for the sound card and other hardware responsible for sound effects

2] Update your game or concerned software

3] Disable Audio effects

4] Disable volume adjustment

5] Change the audio sample rate

Solution 1] Update the driver for the sound card and other hardware responsible for sound effects

1] Press Win + R to open the Run window and type the command devmgmt.msc. Press Enter to open the Device manager.

Type Devmgmt

 

2] Expand the list for Sound, video and game controllers.

3] Right-click on each of the device and select Update driver.

Update Sound Drivers

4] You might also consider uninstalling the drivers (right-click >> uninstall device) and restarting the system. The drivers would get reinstalled automatically.

5] In case you installed a specific game on your device which needs specialized drivers, the same could be downloaded from Intel’s download center.

Another set of drivers that need to be updated are the ones under the Audio inputs and outputs section.

Solution 2] Update your game or concerned software

Software associated with games (eg. Logitech gaming software) if not updated could be one of the cause for the issue.

1] Go to Control Panel >> Programs and Features.

2] Right-click on your gaming software from the list and select Change.

Change Game Software

3] Click on the option to Update or Repair the software.

You might also consider reinstalling the game itself.
