如何在windows上拔下耳机时自动静音

如果你能在拔下耳机的时候自动将电脑的音频输出静音，那不是很好吗？这样可以避免在凌晨不小心吵醒你的室友，或者在公共场合错误地透露你对布兰妮·斯皮尔斯的爱。

当然，您可以使用音量混音器将扬声器和耳机逐个静音。（了解有关在Windows10中自定义声音的更多信息。）但老实说，如果可以使用PowerShell实现自动化，就没有必要这么做。

下面是如何在你摘下耳机时自动静音你电脑的音频，就像智能**一样。

要开始，请打开记事本。然后，将下面的代码粘贴到空白文档中：

[cmdletbinding()]Param()#Adding definiti*** for accessing the Audio APIAdd-Type -TypeDefinition @'using System.Runtime.InteropServices;[Guid("5CDF2C82-841E-4546-9722-0CF74078229A"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]interface IAudioEndpointVolume {// f(), g(), ... are unused COM method slots.

现在需要将文件保存为PS1格式。当您看到保存文件对话框时，从下拉菜单中选择所有文件并调用该文件自动静音.ps1. 文件名本身并不重要，所以只需选择一些容易记住的文件即可。

要激活脚本，右键单击新创建的文件并选择Run。脚本将一直处于活动状态，直到您关闭计算机。

这只是PowerShell提高工作效率的众多方法之一。有很多PowerShell cmdlet可以改善您的Windows体验。
