解决方案

< blockquote>似乎Vista（及其他版本）中的新声音API被重写但仍具有相同的界面。这意味着旧代码仍然可以使用新的API。但是，引入的一个更改是使每个应用程序的卷更改而不是系统范围（通过主卷）。这篇文章更多地讨论了这个问题：

看起来好像你可以通过编写代码来使用旧的界面来使用它，从而使它成为特定于应用程序的。你需要在Vista或更高版本的机器上使用它，但由于它仍然适用于XP（只是不是特定于应用程序），因此它不会是一个大问题（在我看来）。我不知道在XP中允许特定于应用程序的声音设置的任何内容。

It seems as though the new sound APIs in Vista (and beyond) were rewritten but still have the same interfaces. That means that old code will still work with the new APIs. However, the one change that was introduced was to make the volume changes per-application instead of system-wide (via the master volume). Here is an article that talks more about that:

It would seem as though you could use this to your advantage by writing your code to work to the old interface, thus making it application-specific. You would need to use it on a Vista or later machine but since it would still work on XP (just not be application-specific) it wouldn't be that big an issue (in my opinion). I don't know of anything that allows application-specific sound settings in XP.

Tim Hi, the article link that you had pasted seems to be dead. Can you please post a new link?
