将声音输出到声卡的多个通道
我正在尝试用 Java 构建一个程序，该程序能够将声音输出到声卡上的不同输出线。
Java 中怎么可能做到这一点？
I am trying to build a program in Java, which would be able to output sound to different output lines on my sound card.
How is it possible to do in Java?

我不确定您在处理声音方面有什么背景（它可能比我的大），但我认为您拥有的是要定向到多个端口的多条线路？ http://download.oracle.com /javase/7/docs/api/javax/sound/sampled/package-summary.html - 这可能是一个 API，我对此不太了解（我见过一个程序使用了一些东西就像 VoIP 一样）。
顺便说一句，如果您在 Windows 上工作，我相信有关您的声卡的一些信息存储在注册表中，您可能必须从程序更新注册表才能访问它（不确定）。
我希望我能有所帮助:)
I'm not sure what background you have in working with sound (it might be bigger than mine) but what I think you have is a number of lines that you want to direct to a number of ports? http://download.oracle.com/javase/7/docs/api/javax/sound/sampled/package-summary.html - This might be an API for this, which I don't know much about (I've seen a program using something like that with VoIP).
By the way if yr working on Windows, I believe that some information about your soundcard is stored in the registry, and you might have to update the registry from the program to gain access to it (not sure).
I hope I helped somehow :)
查看 Java 声音程序员指南。
为了让它工作，我必须重新配置我的声卡，将其端口公开为单独的“输出”；否则，声卡将根据是否插入耳机自动路由声音。（在 Windows 上。）
Check out the Java sound programmer's guide.
To get this to work I had to reconfigure my sound card to expose its ports as separate "outs"; otherwise the sound card would route the sound automatically depending on whether a pair of headphones were plugged in. (On Windows.)
您可以使用 Jack（Jack 音频连接套件）将声音路由到声卡。它有点复杂，它不适用于pulseaudio，但你可以让它工作。
JnaJack 通过 JNA 提供从 Java 到 Jack API 的接口。这真的很容易。
我在这里更详细地写了它 。
You can use Jack (Jack Audio Connection Kit) to route sound to your soundcard. It is a little complicated, it doesn't work with pulseaudio, but you can make it work.
JnaJack provides an interface from Java to the Jack API via JNA. It's really quite easy.
I wrote it up in more detail here.
