更改 Windows 7 上的默认音频设备

Change default audio device on Windows 7(更改 Windows 7 上的默认音频设备)

问题描述

我希望能够使用 C# 以编程方式更改 Windows 7 上的默认音频输出设备(可能还有一些底层 Win32 API 调用).我已经完成了我的功课，并且我听到了很多来自不同来源的混合评论，所以我想再次问这个问题以获得直接的答案.这真的可能吗(通过 any 手段)?如果是这样，我该怎么做?

I want to be able to change the default audio output device on Windows 7 programatically using C# (and probably some underlying Win32 API calls, as well). I've already done my homework, and I've heard a lot of mixed comments from different sources, so I wanted to ask this question again to get a straight answer. Is this actually possible (through any means)? If so, how would I go about doing this?

请不要建议使用AutoIt"或其他类似程序的解决方案...这是一个 C#/.NET 特定的问题.

And please do not suggest a solution with "AutoIt" or some other similar program... this is a C#/.NET-specific question.

推荐答案

以防万一有人在未来偶然发现这个线程......这里有一些 C++ 代码可以通过调用一些未记录的 Win32 API 来实现.这可以编译成 EXE，然后从 .NET 应用程序静默调用，因此您可以围绕此代码构建一个 .NET 程序.

Just in case anyone stumbles across this thread in the future... here's some C++ code that'll do it by calling some undocumented Win32 APIs. This can be compiled into an EXE and then called silently from a .NET application, so you could build a .NET program around this code.
