如果您 在通知区域^{(Notification Area)}的扬声器图标上看到红色 X 标记^{(a red X mark on the Speaker icon)}，并且当您将鼠标悬停在该图标上时，您会看到一条消息音频服务未^{(The Audio Service is not running)}在您的 Windows 11/10/8/7 PC 上运行，那么这里有一些你需要看看的东西。

Windows 音频服务^{(Windows Audio Service)}未运行

1 ]检查^(Check)Windows 服务^(Services)的状态

运行services.msc以打开 Windows 服务管理器^{(open the Windows Services Manager)}。向下滚动^(Scroll)到Windows Audio Service并双击它以打开其Properties。此服务^(Service)管理基于 Windows 的程序的音频。如果停止此服务，音频设备和效果器将无法正常运行。如果禁用此服务，任何显式依赖它的服务都将无法启动

将启动类型设置为自动^(Automatic)，然后单击开始^(Start)按钮。如果它已经启动，请停止它，然后重新启动它。

您应该确保其依赖^(Dependency) 服务^(Services)已启动并具有自动启动^{(Automatic Startup)}类型：

1. 远程过程调用
2. Windows 音频端点生成器

如果您的系统上存在Multimedia Class Scheduler Service，那么它也应该被 Started 并设置为Automatic。

多媒体类调度程序服务^{(Multimedia Class Scheduler Service)}( MMCSS ) 是一项Windows服务，它允许多媒体应用程序优先访问CPU以进行时间敏感的处理（例如多媒体应用程序）以及优先的磁盘访问，以确保进程不会缺少要处理的数据.

2]运行播放音频疑难解答

Windows 10 包括播放音频疑难解答^{(Playing Audio Troubleshooter)}，您可以通过控制面板^{(Control Panel)}、任务栏搜索^{(Taskbar Search)}或我们免费软件FixWin 10的^{(FixWin 10)}疑难解答^{(Troubleshooters)}选项卡轻松调用。您也可以从Windows 10 中的疑难解答页面访问它。

运行它，看看它是否可以解决您的问题。

3]在干净启动状态下进行故障排除

干净启动^{(Clean Boot)}用于诊断和稍后解决系统问题。在干净启动^(Boot)期间，我们使用最少数量的驱动程序和启动程序启动系统，这有助于隔离干扰软件的原因。

以Clean Boot State启动后，启用一个又一个进程，然后查看是哪个进程导致问题出现。因此，您可以找到罪犯。

如果Windows 无法在本地计算机上启动 Windows 音频服务，请参阅此帖子。^{(See this post if Windows could not start the Windows Audio service on Local Computer.)}

The Windows Audio Service is not running on Windows 11/10

If you see a red X mark on the Speaker icon in the Notification Area, and when you hover over the icon, you see a message The Audio Service is not running on your Windows 11/10/8/7 PC then here are a few things you need to take a look at.

The Windows Audio Service is not running

1] Check the status of Windows Services

Run services.msc to open the Windows Services Manager . Scroll down to Windows Audio Service and double-click on it to open its Properties. This Service manages audio for Windows-based programs. If this service is stopped, audio devices and effects will not function properly. If this service is disabled, any services that explicitly depend on it will fail to start

Set the Startup Type to Automatic and click on the Start button. If it already started, Stop it and then start it again.

You should ensure that its Dependency Services are started and have Automatic Startup type:

1. Remote Procedure Call
2. Windows Audio Endpoint Builder

If the Multimedia Class Scheduler Service is present on your system, that too should be Started and set on Automatic.

Multimedia Class Scheduler Service (MMCSS) is a Windows service that allows multimedia applications to get prioritized access to CPU for time-sensitive processing (such as multimedia applications) as well as prioritized disc access to ensure that the process is not starved of data to process.

2] Run Playing Audio Troubleshooter

Windows 10 includes the Playing Audio Troubleshooter, which you can easily invoke via the Control Panel, the Taskbar Search or the Troubleshooters tab of our freeware FixWin 10. You can also access it from the Troubleshooters Page in Windows 10.

Run it and see if it can fix your problem.

3] Troubleshoot in Clean Boot State

A Clean Boot is used to diagnose and later troubleshoot issues with your system. During a Clean Boot, we start the system with a minimal number of drivers and startup programs which helps isolate the cause with interfering software.

Once you have booted in the Clean Boot State, enable one process after another and see which process makes the problem appear. Thus you can find the offender.
