有时，有效的Windows进程可能无法正常运行，从而导致CPU使用率过高并降低计算机速度。Audiodg.exe就是这样一种服务。
由Windows创建以管理系统的音频，众所周知，此过程经常会导致问题并占用 100% 的处理资源。为什么会出现这样的问题，你该如何处理？在这篇文章中找出答案。
什么是audiodg.exe？
从Windows Vista开始，音频服务像许多其他关键(Windows Vista)Windows服务一样被移至单独的配置文件。这使得用户很难简单地从任务管理器(Task Manager)中错误地关闭它们。
该服务名为Windows Audio Device Graph Isolation，专门用于生成计算机的音频输出。这是一个经过认证的Windows进程，所以它是完全安全的。尝试强制删除或停止它会禁用系统上的所有音频。
是什么原因导致 audiodg.exe高 CPU 使用率(High CPU Usage)？
虽然 audiodg.exe 是真正的Windows进程，但它有时会导致您的计算机出现问题。通常，问题与其高CPU使用率有关，导致您的 PC 有时会滞后。
这可能由于许多因素而发生。音量调整或音频效果等高级(Advanced)音频处理是一个常见原因，因为这些服务会占用相当多的CPU资源。另一个原因可能是您计算机上的声卡驱动程序过时或有故障。(outdated or faulty drivers)
方法#1：禁用音频效果
audiodg.exe 运行时要做的第一件事是禁用PC 上的所有音频增强功能。(audio enhancements)这些增强功能使用CPU实时处理声音输出，这可能会在视频游戏等复杂音频播放过程中导致问题。
- 通过右键单击任务栏上的扬声器图标(the speaker icon)并选择声音(Sounds)来打开声音面板。
- 声音面板允许您修改与计算机上的音频处理相关的所有设置，包括高级效果。
- 切换到播放(Playback)选项卡以获取计算机上所有活动音频设备的列表。向下滚动搜索您喜欢的扬声器。(Search)
- 右键单击(Right-click)活动音频设备并选择Properties。
- 在属性窗口中，切换到增强(Enhancements )选项卡并选中禁用所有增强(Disable all enhancements)选项。按应用(Apply )按钮进行确认。
禁用音频效果后，audiodg.exe 的CPU使用率应该会显着降低，让您的 PC 能够流畅运行。
方法(Method)#2：关闭音量调节
操作系统经常应用的另一个音频增强功能是音量调节(volume adjustment)。虽然不像音频效果那样占用 CPU(CPU)资源，但它仍然会带来一些开销，并且会降低计算机的速度。
- 和以前一样，右键单击任务栏上的扬声器图标并选择声音。(Sounds.)
- 在“通信(Communications )”选项卡中，选择“什么都不做”(Do nothing )单选按钮，然后选择“确定(OK)”进行确认。这将禁用音量调整并减少CPU使用率。
方法(Method)#3：通过降低采样率(Sample Rate)
音频的采样率可以被认为是该声音的“分辨率”。采样率越高，生成的音频质量就越好。另一方面，更高的采样率也需要更多的系统资源，因此如果您的 PC 无法处理它，您可能需要调低它。
- 再次，通过右键单击任务栏上的扬声器图标并选择声音(Sounds)来打开声音面板。
- 现在前往播放(Playback)选项卡并从列表中找到正在使用的音频设备。右键单击它并选择属性(Properties)以配置其设置。
- 在“高级(Advanced)”选项卡中，您将找到选择采样率和位深度的选项。选项的数量取决于所使用的音频设备，但您应该至少有一个质量较低的选项。选择它并选择确定(OK )按钮。
设备的所有音频输出现在将消耗更少的系统资源。这也会降低音质，所以只能作为最后的手段使用。
方法(Method)#4：通过更新音频(Audio)驱动程序
在极少数情况下，audiodg.exe 的问题可能源于过时或不正确的声卡驱动程序。这通常是因为依赖于操作系统安装的默认驱动程序而不是使用制造商提供的正确驱动程序。
大多数指南会告诉您只需从设备管理器(Device Manager)中卸载并重新安装声卡，但我们不(not)推荐这种方法。这样做会让您获得来自Microsoft(Microsoft)的通用驱动程序，而不是针对您的硬件的优化版本。
- 要为您的系统安装正确的驱动程序，请访问您的计算机制造商的网站。对于我们的测试机器，这是Acer。
- 现在您需要选择 PC 的型号。大多数领先的制造商都会有一个可以自动检测此信息的下载应用程序。您可以随时查看设备本身的型号。
- 在显示您计算机的所有驱动程序的页面上，向下滚动直到找到音频驱动程序。下载此文件。
- 运行下载的安装程序以安装声卡驱动程序。这通常需要重新启动系统，然后新的驱动程序才会生效。
在您的计算机上运行最新的驱动程序是解决大多数问题的最简单方法之一，因为制造商会定期更新其驱动程序以修复报告的错误。
如何修复(Fix)audiodg.exe高 CPU 使用率(High CPU Usage)？
Windows 音频图隔离(Windows Audio Graph Isolation)服务通常会显示极高的系统使用率。这是由于音频处理占用的资源超出了您的计算机可以腾出的资源，从而影响了性能。
要解决此问题，您应该尝试禁用计算机上声音设置的所有花里胡哨。这包括音频增强、音量调整或高采样率。如果这不起作用，请尝试更新声卡的驱动程序。确保您从制造商的网站获得最新的优化驱动程序，以提供最佳性能。
How To Fix audiodg.exe High CPU Usage on Windows 11/10
Sometimes, valid Windows processes can run improperly, caυѕing high CPU usаge and slowing down your computer. Audiodg.exe is one such service.
Created by Windows to manage the system’s audio, this process is known to often cause problems and take up 100% of processing resources. Why do such problems occur, and how can you deal with them? Find out in this article.
What is audiodg.exe?
Starting from Windows Vista, audio services were moved to a separate profile like many other critical Windows services. This makes it difficult for the user to simply shut them down by mistake from the Task Manager.
Named Windows Audio Device Graph Isolation, this service is dedicated to producing your computer’s audio output. It is a certified Windows process, so it’s completely safe. Trying to delete or stop it forcefully will disable all audio on your system.
What Causes audiodg.exe High CPU Usage?
While audiodg.exe is a genuine Windows process, it can sometimes cause issues on your computer. Usually, the problem is related to its high CPU usage, making your PC lag at times.
This can happen due to many factors. Advanced audio processing like volume adjustment or audio effects is a common reason, as these services take up quite a bit of CPU power. Another reason can be outdated or faulty drivers for the soundcard on your computer.
Method #1: Disable Audio Effects
The first thing to do when audiodg.exe is acting up is to disable all audio enhancements on your PC. These enhancements use the CPU to process the sound output in real-time, which can cause issues during complex audio playback such as video games.
- Open the sound panel by right-clicking on the speaker icon on the taskbar and select Sounds.
- The sound panel allows you to modify all settings related to audio processing on your computer, including advanced effects.
- Switch to the Playback tab to get a list of all the audio devices active on your computer. Search for your preferred speakers by scrolling down.
- Right-click on the active audio device and select Properties.
- In the properties window, switch to the Enhancements tab and check the Disable all enhancements option. Press the Apply button to confirm.
With audio effects disabled, the CPU usage of audiodg.exe should significantly decrease, allowing your PC to function smoothly.
Method #2: By Turning Off Volume Adjustment
Another audio enhancement often applied by the operating system is volume adjustment. While not as CPU intensive as audio effects, it still carries some overhead and can slow down your computer.
- As before, right-click on the speaker icon on your taskbar and select Sounds.
- In the Communications tab, select the Do nothing radio button and select OK to confirm. This will disable volume adjustment and reduce CPU usage.
Method #3: By Lowering the Sample Rate
The sample rate of audio can be considered the “resolution” of that sound. The higher the sample rate, the better the quality of the audio that is produced. On the flip side, higher sample rates also require more system resources, so you might want to tone it down if your PC cannot handle it.
- Once again, open the sound panel by right-clicking on the speaker icon on the taskbar and select Sounds.
- Now head to the Playback tab and find the audio device being used from the list. Right-click on it and select Properties to configure its settings.
- In the Advanced tab, you will find the option to choose a sample rate and bit depth. The number of options depends on the audio device used, but you should have at least one lower-quality option. Select it and select the OK button.
All audio output from the device will now consume lesser system resources. This will also reduce the sound quality, so use it only as a last resort.
Method #4: By Updating Audio Drivers
Very rarely, it is possible that the issues with audiodg.exe stem from outdated or incorrect sound card drivers. This usually happens because of relying on the default drivers installed by the operating system rather than using the correct drivers from the manufacturer.
Most guides will tell you to simply uninstall and reinstall the sound card from the Device Manager, but we do not recommend that approach. Doing so will get you the general-purpose drivers from Microsoft, not the optimized version meant for your hardware.
- To install the correct drivers for your system, head to the website of your computer’s manufacturer. For our test machine, this is Acer.
- Now you need to choose the model number of your PC. Most leading manufacturers will have an application for download that can auto-detect this information. You can always check the model number on your device itself.
- On the page showing all the drivers for your computer, scroll down until you find the audio drivers. Download this file.
- Run the downloaded setup to install the sound card drivers. This will usually require a system restart, after which the new drivers will take effect.
Running the latest drivers on your computer is one of the easiest ways to solve most problems, as manufacturers periodically update their drivers to fix reported bugs.
How To Fix audiodg.exe High CPU Usage?
The Windows Audio Graph Isolation service can often show extremely high system usage. This is caused by the audio processing taking up more resources than your computer can spare, affecting performance.
To fix this issue, you should try disabling all bells and whistles of the sound settings on your computer. This includes audio enhancements, volume adjustment, or a high sample rate. If that doesn’t work, try updating the drivers of your soundcard. Make sure you get the latest optimized drivers from the manufacturer’s website to give you the best performance.
