The transition to the modern Windows 10 operating system for most users went without difficulties and negative consequences.

However, for some devices (usually quite outdated), installing a new operating system took a lot of effort and patience.

One of these problems is the constant "slowdown" of the computer when running programs, games and applications that use the microphone functions or capture a monitor image.

As a rule, faced with such obstruction, the user opens the "Task Manager" in search of a "difficult" process and sees that "Isolation of Windows Audio Device Graphs" comes first in terms of "pressure" on the CPU.

What is this process, why and why it has such an effect on the computer, and how to get rid of the "trouble" - this is what we will tell you in this article.

What is windows audio device graph isolation

This process was called “audiodg.exe” on Windows 7, and it is responsible for implementing various audio effects, which, according to current realities, are simply necessary for comfortable work on a computer.

Therefore, "audiodg.exe" should not have a similar effect on the correct operation of the operating system. Therefore, we can say with confidence that the workload of this process is not the initial cause of the problem, but only its consequence.

Option 1

Since the process in question relates to system ones, the first thing to do is to check the integrity of system files. Diagnose the OS as follows:

  • Click on the “Search” icon located in the lower left corner of the desktop (for Windows 10) or click on “Start”, select the search line with the caption “Find programs and files” (for Windows 7) and enter “Command Prompt”.
  • Using the right mouse button, click on the found file and select “Run as administrator”.

Run Commad Promt as Administrator

  • In the console that opens, enter the command “sfc / scannow” and wait for the scan to complete and fix the errors of the system components.

Input un the console: sfc / scannow

It should be noted that this scan can take a lot of time, and you should be patient.

If the scan did not reveal problems, and the situation is not resolved, then go to the next solution to the problem with the process "audiodg.exe".

Option 2

The second method assumes that the reason for the heavy load has become - the Windows Audio service is not working correctly:

Press the key combination “WIN + P” and enter “services.msc”.

Open Windows Services with cmmand: services.msc

  • You will see a window with the name "Services" and a long list on the right side of the window. In this list, you need to find "Windows Audio".
  • When this service is found, click on it to highlight it and click on the “Restart” button.
  • Or right-click on it, select "Properties", then go to the "Startup Type" line, select "disable", click "OK" and close the properties window. Then go back and select “Automatic” in the Startup Type.

Restart Windows Audio Service

Option 3

If the problem arises with applications or programs that use external connected devices, then this may be due to the unstable power supply of the equipment. Therefore, try switching the headset, webcam or headphones to another usb port.

Option 4

If the system was not checked for updates, then you can skip the first three options, you should check the relevance and correctness of the software drivers used.

You can do this manually by first downloading the necessary drivers from the developer"s site, or use specialized software (for example, “DriverPack Solution” or “DriverBooster”).

Option 5

The final way to solve this problem is banal disabling sound effects. This can be done as follows:

Depending on your operating system version, open “Control Panel” and go to “Sound”.

Open - Control Panel - and then SoundIn the window that opens, in the first tab "Playback" double-click the properties of the speakers.

Double click in the Speakers Properties

Go to the "Enhancements" tab and check the "Disable all sound effects" line.

In the Enhancements tab and check the Disable all sound effects

Next, click the "Advanced" tab and uncheck the lines "Allow applications to take exclusive control of this device" and "Give exclusive mode applications priority".

Then  click the (Advanced) tab and uncheck the lines: Allow applications to take exclusive control of this device

Go back to the original "Sound" window, open the "Record" tab and activate and clear the above parameters by analogy.

Next, based on option 2, restart the Windows Audio service and verify that the application or game is working.


In conclusion, it should be added that in General, the problem does not arise out of the blue: something or someone should put direct pressure on the correctness of the system processes.

Therefore, it is not superfluous to check the General condition of the computer in all available ways and in the future to keep it up to date and not cluttered.
