如何在windows上拔下耳機時自動靜音

下面是如何在你摘下耳機時自動靜音你電腦的音訊，就像智慧手機一樣。...

如果你能在拔下耳機的時候自動將電腦的音頻輸出靜音，那不是很好嗎？這樣可以避免在凌晨不小心吵醒你的室友，或者在公共場合錯誤地透露你對布蘭妮·斯皮爾斯的愛。

當然，您可以使用音量混音器將揚聲器和耳機逐個靜音。（瞭解有關在Windows10中自定義聲音的更多信息。）但老實說，如果可以使用PowerShell實現自動化，就沒有必要這麼做。

下面是如何在你摘下耳機時自動靜音你電腦的音頻，就像智能**一樣。

要開始，請打開記事本。然後，將下面的代碼粘貼到空白文檔中：

[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.

現在需要將文件保存為PS1格式。當您看到保存文件對話框時，從下拉菜單中選擇所有文件並調用該文件自動靜音.ps1. 文件名本身並不重要，所以只需選擇一些容易記住的文件即可。

要激活腳本，右鍵單擊新創建的文件並選擇Run。腳本將一直處於活動狀態，直到您關閉計算機。

這只是PowerShell提高工作效率的眾多方法之一。有很多PowerShell cmdlet可以改善您的Windows體驗。
