推荐答案

在Linux下，你可以使用mpg123的命令来播放mp3不同的声卡。

On Linux you can use mpg123 command to play mp3 on different soundcards.

public class SoundTest {
    public static void main(String[] args) {
    //play mp3
        try {
         //my first soundcard is CA0106 with id: CARD=CA0106
            java.lang.Process p1 = Runtime.getRuntime().exec(new String[]{"mpg123", "-asysdefault:CARD=CA0106", "audio/1.mp3"});
         //my second soundcard is CARD=Intel (internal motherboard souncard)
            java.lang.Process p2 = Runtime.getRuntime().exec(new String[]{"mpg123", "-asysdefault:CARD=Intel", "audio/2.mp3"});
        } catch (Exception e) {
            e.printStackTrace();
        }
    //play wav
        try {
        java.lang.Process p3 = Runtime.getRuntime().exec(new String[]{"aplay", "audio/audio1.wav", "-Dsysdefault:CARD=Intel"});
        java.lang.Process p4 = Runtime.getRuntime().exec(new String[]{"aplay", "audio/audio2.wav", "-Dsysdefault:CARD=CA0106"});
     } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

声卡的ID，您可以通过命令来获得 aplay -L
这不是一个Java的方式，但对我的工作非常有用。

Soundcard ids you can get via command aplay -L It's not a Java way but was useful for my task.
