就像饥饿的动物一样，您个人计算机上的所有内容总是想占用/吃掉尽可能多的资源。Windows PC 上的占用者是在用户不知道的情况下不断在后台运行的各种应用程序、进程和服务，占用的资源是CPU和临时内存，即RAM。
高CPU使用率在(CPU)Windows中是一个非常常见的问题，当不需要的应用程序或进程从处理器中吸取比最初预期的更多的功率时，就会发生高 CPU 使用率问题。当您的个人计算机接近尾声(high CPU usage)或您正在执行需要大量处理能力的操作（例如：在(For example:)Premiere Pro上编辑视频或在Photoshop中处理多个图层，以及甚至不要让我们开始玩游戏）。高CPU使用率最终也可能导致永久性处理器损坏。
Windows Audio Device Graph Isolation是众多因提示CPU使用率过高而臭名昭著的进程之一。它是 Windows 众多后台进程之一，是音频处理和输出必不可少的进程。
修复 Windows Audio Device Graph Isolation 高 CPU 使用率(Fix Windows Audio Device Graph Isolation high CPU usage)
在本文中，我们将讨论为什么音频设备图隔离(Audio Device Graph Isolation)进程会导致CPU使用率高，以及如何减少其CPU消耗以重新获得一些急需的处理能力。
什么是 Windows 音频设备图隔离过程以及为什么它会导致 CPU 使用率高？(What is the Windows Audio Device Graph Isolation process & why it causes high CPU usage? )
首先，音频设备图隔离(Audio Device Graph Isolation)进程是官方合法的Windows进程，而不是病毒或恶意软件(malware)。该进程充当Windows中的主要音频引擎，负责处理数字信号处理。简而言之，它允许第三方应用程序在您的计算机上运行声音。该过程还控制Windows提供的声音增强功能。
但是，该过程与Windows 音频(Windows Audio)服务是分开的，这允许第三方声卡/音频硬件制造商包含他们自己的增强服务，而无需修改Windows 音频(Windows Audio)服务。
那么如果是合法服务，为什么会导致 CPU 使用率高呢？(So if it is a legitimate service, why does it cause high CPU usage?)
通常，Audio Device Graph Isolation进程的 CPU(’ CPU)使用率可以忽略不计，在应用音频效果时，使用率会略有增加，然后回落到零。高CPU(CPU)使用率的可能原因是损坏/安装不当的音频增强驱动程序和启用的音效。
高CPU(CPU)使用率的另一种解释是某些恶意软件或病毒可能将自己伪装成进程并在您的计算机上找到了自己的方式。要检查您计算机上运行的音频设备图形隔离(Audio Device Graph Isolation)进程是否是病毒，请按照以下步骤操作 -
1. 我们首先启动任务管理器(Task Manager)。根据您的方便使用以下任何一种方法打开它。(Use)
一种。在Windows搜索栏中键入任务管理器（ (Type Task Manager)Windows键 + S），然后在搜索返回时单击打开。(Open)
湾。右键单击任务栏并选择任务管理器(Taskbar and select Task Manager)。
C。右键单击(Right-click)开始按钮（或按Windows键 + X）并从高级用户/开始菜单中选择任务管理器。(Task Manager)
d。通过按组合键Ctrl + Shift + ESC.直接启动任务管理器。(Task Manager)
2. 在 Processes 选项卡下，找到 Windows Audio Device Graph Isolation 进程并右键单击它。( locate the Windows Audio Device Graph Isolation process and right-click on it. )
3. 从随后的选项/上下文菜单中，选择打开文件位置(Open file location)。
4. 默认情况下，进程源自C:\Windows\System32文件夹，应用程序文件名为Windows Audio Device Graph Isolation。尽管在某些系统中，应用程序可能被命名为audiodg。
如果您的应用程序文件/进程的名称或地址与上述位置 (C:WindowsSystem32) 不同，则您的个人计算机上运行的音频设备图隔离(Audio Device Graph Isolation)进程可能是病毒/恶意软件应用程序。在这种情况下，您需要运行防病毒扫描并清除病毒(run an antivirus scan and get rid of the virus)。您可以选择使用一些专门的第三方防病毒软件或内置的Windows防御者。
尽管如此，进程文件可能存在于其默认位置，但仍会导致CPU使用率过高。不幸的是，我们不能只是禁用或结束该过程，因为它对于音频输出至关重要，并且禁用它会使您的计算机完全静音。相反，我们将不得不从根本上解决问题。
如何修复音频设备图隔离高 CPU 使用率？(How to fix Audio Device Graph Isolation high CPU usage?)
修复音频设备图隔离的高CPU使用率不是火箭科学，需要您执行以下操作之一。首先(First)，如果您计算机上运行的进程是病毒，请运行防病毒扫描以将其删除。如果不是，请尝试禁用所有音效并卸载有问题的音频驱动程序。该问题也可以通过重新安装 Skype(reinstalling Skype)来解决，有时也可以通过禁用“嘿 Cortana”功能来解决。

让我们知道上述哪种方法修复了音频设备图隔离(fixed Audio Device Graph Isolation’s high CPU usage)在您的个人计算机上的高 CPU 使用率。
Fix Windows Audio Device Graph Isolation high CPU usage
Like a hungry animal, everything on your personal computer alwаys wants to hog/eat up as many resоυrceѕ as рossible. The hoggers on a Windows PC are thе various appliсations, processеs, and ѕervices that constantly run in the background without the user ever knowing about them, and the resources being hоggеd upon are the CPU and temporarу memory, i.e, RAM.
High CPU usage is a pretty common problem in Windows and occurs when an unwanted application or process siphons more power out of the processor than it is originally meant to. The high CPU usage problem becomes even more infuriating when your personal computer is nearing its end days or you are performing an action that requires a lot of processing power (For example: Editing a video on Premiere Pro or working with multiple layers in Photoshop, and don’t even get us started on games). High CPU usage can also eventually lead to permanent processor damage.
The Windows Audio Device Graph Isolation is one of the many processes infamous for prompting high CPU usage. It is one of Windows’ many background processes and is an essential process for audio processing and output.
Fix Windows Audio Device Graph Isolation high CPU usage
In this article, we will be addressing why the Audio Device Graph Isolation process causes high CPU usage and how to reduce its CPU consumption to gain back some much-needed processing power.
What is the Windows Audio Device Graph Isolation process & why it causes high CPU usage?
To start off, Audio Device Graph Isolation process is an official and legitimate Windows process and not a virus or malware. The process serves as the primary audio engine in Windows and is responsible for handling digital signal processing. In simpler words, it allows third-party applications to run sound on your computer. The process also controls the sound enhancements provided by Windows.
The process is, however, separate from the Windows Audio service and this allows third-party sound card/audio hardware manufacturers to include their own enhancement services without tinkering with the Windows Audio service.
So if it is a legitimate service, why does it cause high CPU usage?
Normally, the Audio Device Graph Isolation process’ CPU usage is negligible, and when audio effects are being applied, the usage will increase slightly before falling back to zero. The possible reasons for high CPU usage are corrupt/poorly installed audio enhancement drivers and the enabled sound effects.
Another explanation for the high CPU usage is some malware or a virus may have disguised itself as the process and found its way on your computer. To check if the Audio Device Graph Isolation process running on your computer is a virus or not, follow the below steps-
1. We start by launching the Task Manager. Use any of the below methods as per your convenience to open it.
a. Type Task Manager in the Windows search bar (Windows key + S) and click on Open when the search returns.
b. Right-click on the Taskbar and select Task Manager.
c. Right-click on the start button (or press Windows key + X) and select Task Manager from the power user/start menu.
d. Launch Task Manager directly by pressing the key combination Ctrl + Shift + ESC.
2. Under the Processes tab, locate the Windows Audio Device Graph Isolation process and right-click on it.
3. From the ensuing options/context menu, select Open file location.
4. By default, the process originates from the C:\Windows\System32 folder, and the application file is called Windows Audio Device Graph Isolation. Although, in some systems, the application may be named audiodg.
If the name or address of your application file/process differs from the above-stated location (C:\Windows\System32), the Audio Device Graph Isolation process running on your personal computer is likely a virus/malware application. In this case, you will need to run an antivirus scan and get rid of the virus. You can either choose to use some specialized third-party antivirus software or the built-in Windows defender.
Nevertheless, the process file can be present at its default location and still cause high CPU usage. Unfortunately, we can’t just disable or end the process as it is essential for audio output, and disabling it will make your computer go completely silent. We will instead have to solve the problem from its root.
How to fix Audio Device Graph Isolation high CPU usage?
Fixing Audio Device Graph Isolation’s high CPU usage is no rocket science and requires you to perform one of the below actions. First up, if the process running on your computer is a virus, run an antivirus scan to remove it. If it isn’t, try disabling all the sound effects and uninstalling the problematic audio drivers. The problem has also been known to resolve by reinstalling Skype and sometimes by disabling the ‘Hey Cortana’ feature.
Run an Antivirus Scan using Windows Defender
If the process is indeed a virus, follow the below steps to run an antivirus scan using the Windows Defender (you may also run a virus scan from any third-party application you might have installed on your computer). Although if it isn’t a virus, you can directly skip to the next method.

(You can also access Sound settings by right-clicking on the Speakers icon on your taskbar, selecting Open sound settings, and then clicking on the Sound Control Panel in the next window. Certain Windows versions will directly have the option to open Playback devices when the user right-clicks on the speaker icon.)
3. Select your primary (default) playback device and click on the Properties button at the bottom-right of the window.
4. Switch to the Enhancements tab of the Speaker Properties window.
5. Here, you will find a list of sound effects that are being applied to the sound emanating from your playback device. The list of available Windows sound effects includes Environment, Voice Cancellation, Pitch Shift, Equalizer, Virtual Surround, Loudness Equalization.
6. Check/tick the box next to Disable all sound effects by clicking on it.
7. If you do not find the option to Disable all sound effects (like in the below picture), one by one, uncheck the boxes next to individual sound effects until all of them have been disabled.
8. Once you have disabled all sound effects, click on the Apply button to save your changes.
9. Repeat steps 3 to 6 for every other Playback device you have and restart your personal computer once done.
