Java Sound API在您的计算机上找到哪些输出和记录端口？

我正在使用Java Sound API,如果我想调整记录卷,我需要对操作系统公开给Java的硬件进行建模.事实证明,所呈现的内容有很多种.

因此,我谦虚地要求任何人能够帮助我在他们的计算机上运行以下内容并回发结果,以便我可以了解那里有什么.

提前感谢任何可以提供帮助的人:-)

      for (Mixer.Info thisMixerInfo : AudioSystem.getMixerInfo()) {
        System.out.println("Mixer: "+thisMixerInfo.getDescription()+

        Mixer thisMixer = AudioSystem.getMixer(thisMixerInfo);
        for (Line.Info thisLineInfo:thisMixer.getSourceLineInfo()) {

} 

所有应用程序都打印出关于操作系统的一行,关于JVM的一行,以及关于可能与录制硬件有关的硬件的几行.例如,在我工作的PC上,我得到以下内容:

正如Uri所说,Java Sound API肯定不会在Mac OS X上产生任何有趣的结果:

Mixer: software mixer and synthesizer [Java Sound Audio Engine]

另外,我应该注意到我使用的是soylatte-1.0.3,而不是使用Apple的开发工具分发的相当老的JDK.
