如何在Vista中设置默认音频设备 [英] How can I set default audio device In Vista

问题描述

你好，
我有一个必须尽快解决的问题，不幸的是，我一直在寻找大量信息并发布在许多论坛中，这仍然没有解决.
我可以使用IMMDeviceEnumerator :: GetDefaultAudioEndpoint函数获取默认的渲染端点设备，并通过其他接口获取所有端点，但是我没有找到类似于"SetDefaultEndpoint"的函数，我无法在程序中更改默认端点设备，如何通过代码在Vista中设置默认音频设备?
谢谢.

推荐答案

Microsoft不提供用于设置默认音频设备的编程方法.您可能可以直接操纵注册表来更改默认音频设备.在Windows XP及以下版本上，以下各项将起作用:

Hi,

Microsoft does not provide a progmatic method for setting the default audio device. You could probably manipulate the registry directly to change the default audio device. On Windows XP and below the following will work:

Changing your Windows audio device programmatically using VC++[^]

On Vista and above the registry key is located at:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio

There is an undocumented/unsupported COM interface IPolicyConfig which is demonstrated here: http://eretik.omegahg.com/download/DefSound.rar[^]
