从WMI Provider Host(WMI Provider Host)到Client Server Runtime ，有很多Windows系统进程的名称很长，令人困惑。然而，如果你问大多数Windows用户他们在做什么，他们不会知道。那是因为这些系统进程被设计为工作，但不被看到（除非有问题）。
Windows 音频设备图隔离(Windows Audio Device Graph Isolation)过程进一步证明了这一点，名称很长，但没有太多指示（除了音频）它可能在您的 Windows PC 上执行的操作。为了帮助您了解它的作用，以下是您需要了解的有关Windows 10中的(Windows 10)Windows 音频设备图隔离(Windows Audio Device Graph Isolation)过程的所有信息。
什么是 Windows 10 中的 Windows 音频设备图隔离？(What Is Windows Audio Device Graph Isolation in Windows 10?)
Windows 音频设备图隔离(Windows Audio Device Graph Isolation )进程（或audiodg.exe ）是(audiodg.exe)Windows操作系统中的重要组件。顾名思义，它在Windows PC(Windows PCs)如何处理音频输出方面发挥着重要作用。
audiodg.exe 进程是Windows的音频引擎，允许第三方服务访问您的声音输出设备。它还负责音频增强功能，例如用于耳机的 Windows Sonic(Windows Sonic for Headphones)，这有助于提高耳机的音频质量。
它提供对其他应用程序、服务和开发人员可以使用的Windows音频的访问。(Windows)音频(Audio)产品，如耳机，可以附带自己的增强软件——这些应用程序将使用Windows 音频设备图隔离(Windows Audio Device Graph Isolation)过程，而不是直接与Windows 音频(Windows Audio)服务接口。
在某些情况下，您可能会发现Windows Audio Device Graph Isolation服务被硬件制造商的另一个数字信号处理器（例如Creative）所取代。这没什么好担心的，但是如果您不认识硬件，您可以快速检查并删除任何潜在的恶意软件(remove any potential malware)。
audiodg.exe 进程提供更高的安全性和稳定性，因为不稳定的应用程序或服务使单独的Windows 音频(Windows Audio)服务崩溃可能会导致蓝屏死机 (BSOD) 错误(cause a Blue Screen of Death (BSOD) error)。由于audiodg.exe 控制了Windows 的数字信号处理功能，这种情况发生的可能性要小得多。
它还使您能够禁用增强功能，而不会影响其他地方的Windows 音频(Windows Audio)设置。
Windows 音频设备图隔离安全吗？(Is Windows Audio Device Graph Isolation Safe?)
禁用重要的系统进程（如Windows 音频设备图隔离(Windows Audio Device Graph Isolation)进程）通常不是一个好主意。禁用它需要您禁用主要的Windows 音频(Windows Audio)服务，这将削弱所有Windows音频输出。但是，这会让你没有声音。
值得庆幸的是，audiodg.exe 可以完全安全地继续运行。在大多数情况下，使用最少的系统资源不会引起任何问题。
Windows 音频设备图形隔离(Windows Audio Device Graph Isolation)服务的大多数问题通常可以追溯到可能正在访问它的第三方应用程序或服务。如果您最近安装了新硬件以及音频控制软件，那么正在使用的其他增强功能可能会导致不稳定和CPU使用率过高。
如果是这种情况，那么您可以禁用所有Windows音频增强功能。这应该会导致CPU使用率恢复正常，并使 audiodg.exe 进程没有太多事情可做，保持活动状态，但在其他方面保持沉默。
有时，恶意软件伪装成其他服务（例如 audiodg.exe 服务）可能会出现问题，尽管这不太可能发生。如果您担心，可以按照以下部分中的步骤快速检查是否是这种情况。

了解 Windows 系统功能(Understanding Windows System Features)
在大多数情况下，audiodg.exe 和msmpeng.exe等进程应该可以正常工作，无需任何额外输入。(msmpeng.exe)作为Windows系统进程，它们的作用是提供您将在 PC 上看到的许多功能，因此不必担心。如果您仍然担心，快速的恶意软件扫描(quick malware scan)应该会让您放心。
当系统进程确实出现问题时，通常可以通过定期系统维护来解决。可以监控高 CPU 峰值(High CPU spikes can be monitored)是否存在问题，修复计算机风扇(fixing your computer fans)等解决方案有助于降低对 PC 的需求。如果一切都失败了，请考虑升级您的 PC(upgrading your PC)以提供 Windows 额外资源。
What Is Windows Audio Device Graph Isolation (and Is It Safe)
Thеre are plenty of Windows system procеssеs with long, confusing names, from the WMI Provider Host to the Client Server Runtime. If you ask most Windows users what they do, however, they won’t know. That’s because these system processes are designed to work, but not be seen (unless there’s a problem).
The Windows Audio Device Graph Isolation process is further proof of this, with a long name, but not much indication (beyond audio) what it might be doing on your Windows PC. To help you understand what it does, here’s everything you need to know about the Windows Audio Device Graph Isolation process in Windows 10.
What Is Windows Audio Device Graph Isolation in Windows 10?
The Windows Audio Device Graph Isolation process (or audiodg.exe) is an important component in the Windows operating system. As the name might suggest, it plays an important part in how audio output is handled by Windows PCs.
The audiodg.exe process is the audio engine for Windows, allowing third-party services access to your sound output devices. It also has responsibility for audio enhancement features, like Windows Sonic for Headphones, which helps to improve audio quality for headphones.
It provides access to Windows audio that other apps, services, and developers can use. Audio products, like headphones, could come with their own enhancement software—these apps will use the Windows Audio Device Graph Isolation process, rather than interfacing with the Windows Audio service directly.
In some cases, you may find that the Windows Audio Device Graph Isolation service is replaced with another digital signal processor from a hardware manufacturer (such as Creative). This isn’t anything to be alarmed about, but if you don’t recognize the hardware, you can check and remove any potential malware quickly.
The audiodg.exe process offers greater security and stability, as an unstable app or service crashing the separate Windows Audio service could cause a Blue Screen of Death (BSOD) error. With audiodg.exe taking control of Windows’ digital signal processing features, this is much less likely to occur.
It also gives you the ability to disable enhancements without affecting Windows Audio settings elsewhere.
Is Windows Audio Device Graph Isolation Safe?
It isn’t usually a good idea to disable important system processes like the Windows Audio Device Graph Isolation process. Disabling it will require you to disable the main Windows Audio service, which will cripple all Windows audio output. However, this would leave you without sound.
Thankfully, audiodg.exe is entirely safe to leave running. In most cases, it shouldn’t cause any issues, with minimum system resources used.
Most issues with the Windows Audio Device Graph Isolation service can usually be traced to third-party apps or services that may be accessing it. If you’ve installed new hardware recently, along with audio control software, then the additional enhancements being used could result in instability and high CPU usage.
If that’s the case, then you can disable all Windows audio enhancements. This should cause the CPU usage to return to normal and leave the audiodg.exe process without much to do, remaining active, but otherwise silent.
There can sometimes be problems with malware pretending to be other services, like the audiodg.exe service, although this is unlikely. If you’re worried, you can quickly check if this is the case by following the steps in a section below.
How to Troubleshoot Windows Audio Device Graph Isolation High CPU Usage Issues
Most of the time, the audiodg.exe process should run without issue. You should only see it using system resources when audio enhancements are activated by a third-party app or service, and should quickly return to zero usage.
However, if you spot Windows Audio Device Graph Isolation with high CPU usage that doesn’t return to normal, this could point to a problem with your audio settings and enhancements. First, check that no third-party audio software is running on your PC, including audio control software from hardware manufacturers.
That also includes any audio enhancement software like equalizers, surround sound management, and audio mixers that you may have installed. Software like this can cause CPU usage spikes in the audiodg.exe process.
If you find software like this running, close it and ensure that it’s no longer running in Windows Task Manager. If your system resources don’t return to normal after this point, then Windows Audio Device Graph Isolation high CPU usage can usually be resolved by disabling audio enhancements entirely.
- To do this, find the speaker system tray icon in the notifications area on your taskbar. Right-click it, then select the Sounds option.
- In the Playback tab, select your audio output device, then select the Properties button.
- In the Enhancements tab of the Properties window, you’ll see a list of available enhancements. Select the Disable all enhancements checkbox to switch these off, then select OK to apply the new settings.
This should disable the audio enhancements and return the audiodg.exe process to normal. If it doesn’t, you may need to run the Windows Troubleshooter to investigate audio issues instead.
- To run this, right-click the Start menu and select the Settings option.
- In the Settings menu, select Update & Security > Troubleshoot > Additional troubleshooters > Playing audio > Run the troubleshooter. This will launch the Windows Troubleshooter tool for Windows Audio and all related services and processes.
Windows Troubleshooter will automatically scan for and attempt to fix any problems with your Windows Audio settings and services, including audiodg.exe. It will also list any problems that it detects but can’t fix itself, allowing you to troubleshoot manually.
How to Check Whether Windows Audio Device Graph Isolation Is a Genuine System Process
Reports of malware hiding as system processes are uncommon, but it has been known to happen. If you want to be sure that the Windows Audio Device Graph Isolation process is a genuine system process, you can do so using Windows Task Manager.
- Right-click the taskbar and select the Task Manager option to begin.
- In the Task Manager window, right-click Windows Audio Device Graph Isolation in the Processes tab (or audiodg.exe in the Details tab), then select the Open file location option.
- This will open Windows File Explorer. If the location of the audiodg.exe file is in the C:\Windows\System32 folder, you can be confident that this is a genuine Windows process.
If the file is elsewhere, however, then this could indicate a likely malware infection, which you’ll then need to scan and remove it using Windows Defender or a third-party alternative.
Understanding Windows System Features
Processes like audiodg.exe and msmpeng.exe should, in most cases, work fine without any additional input. As Windows system processes, they act to provide the many features that you’ll see on your PC, and shouldn’t be a cause for concern. If you’re still worried, a quick malware scan should help put your mind at ease.
When system processes do show issues, it can usually be resolved through regular system maintenance. High CPU spikes can be monitored for problems, with solutions like fixing your computer fans helping to reduce the demands on your PC. If all else fails, considering upgrading your PC to give Windows extra resources.
