The analysis of the main Windows system processes, which are common to all computers, is useful in case one of them should occupy too much RAM or too much CPU in the task manager. One of these internal processes of Windows 10 and Windows 8 is called Windows Sound Device Graphic Isolation, whose name is so particular that it is also difficult to imagine what it means, what it is used for and why it can use too many resources .

The Windows Audio Device Graphics Isolation process is the primary Windows 10 audio engine.
It handles digital signal processing, including the advanced audio enhancement effects provided by Windows.
The process is related to the system file audiodg.exe and cannot be terminated manually.
Furthermore, this process is separate from the standard Windows Audio service, that is, the one that allows the PC to make sounds and music heard.
Audio device graphic isolation allows audio hardware manufacturers (speakers or amplifiers) to provide digital enhancements without having to replace the Windows Audio service.
This improves stability and prevents a crash of the Windows Audio service, which is a cornerstone of the system and would cause a computer crash.
By isolating digital audio signal processing, crashes due to audio errors are certainly more contained.
This type of isolation also ensures that Windows has the ability to disable audio accessories from the operating system, regardless of the type of hardware you are using.
Note that in some cases, sound card manufacturers replace this process with that of the proprietary driver and you will not see any Windows Sound Device Graphics Isolation in the Task Manager.
In the event that this process of graphic isolation occupies too many resources, CPU and memory, the problem may depend on the driver of the sound card, which may have been poorly written.
Under normal conditions, the audiodg process should use 0% of the CPU and a really low amount of memory.
If this is not the case, it means that there is a problem which, fortunately, can be easily solved by deactivating the audio improvements in Windows .
Then go to Control Panel> Audio, select the sound card used and press the Properties button.
From the Properties, go to Improvements and click the " Disable all improvements " option.
If disabling audio enhancements doesn't resolve anything, try searching for a newer sound card driver or turning off audio enhancement options in the audio manager.
In my PC there is a problem with this process because it occupies fixed 1% of CPU, which depends on an old driver that runs a sound card that does not support Windows 10 (in practice I can not do anything about it).
You cannot end or disable the " Windows Sound Device Graphics Isolation " process without disabling the main Windows Audio service.
Since this Audio Isolation is an official component of Windows, it will never be a virus (although in the future malware may also be hiding in this process).
To check that it is not a malware, in the Task Manager, right-click on it, press Open file path, and verify that it refers to the audiodg.exe file inside C: Windows / system32 .
