UIManager.put("AuditoryCues.playList",
UIManager.get("AuditoryCues.allAuditoryCues"));

看看这个：
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class Audio extends JFrame
{

/**
*
*/
private static final long serialVersionUID = 1L;

public Audio()
{
super("Auditory Popups");
setDefaultCloseOperation(EXIT_ON_CLOSE);
UIManager.put("AuditoryCues.playList", UIManager.get("AuditoryCues.defaultCueList"));
UIManager.put("OptionPane.questionSound", "sounds/OptionPaneError.wav");
JPanel contentPane = (JPanel) this.getContentPane();
JPanel center = new JPanel();
ButtonGroup buttonGroup = new ButtonGroup();
JRadioButton defaultAudio = new JRadioButton("Default", true);
center.add(defaultAudio);
buttonGroup.add(defaultAudio);
defaultAudio.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
UIManager.put("AuditoryCues.playList", UIManager.get("AuditoryCues.defaultCueList"));
}
});
JRadioButton offAudio = new JRadioButton("Off", false);
center.add(offAudio);
buttonGroup.add(offAudio);
offAudio.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
UIManager.put("AuditoryCues.playList", UIManager.get("AuditoryCues.noAuditoryCues"));
}
});
JRadioButton onAudio = new JRadioButton("On", false);
center.add(onAudio);
buttonGroup.add(onAudio);
onAudio.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
UIManager.put("AuditoryCues.playList", UIManager.get("AuditoryCues.allAuditoryCues"));
}
});
contentPane.add(center, BorderLayout.CENTER);
JButton confirmButton = new JButton("Confirmation Dialog");
contentPane.add(confirmButton, BorderLayout.SOUTH);
confirmButton.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
int result = JOptionPane.showConfirmDialog(Audio.this, "Confirm?");
if (result == JOptionPane.YES_OPTION)
{
JOptionPane.showMessageDialog(Audio.this, "Confirmed");
}
else
{
JOptionPane.showMessageDialog(Audio.this, "Rejected");
}
}
});
JButton messageButton = new JButton("Message Dialog");
contentPane.add(messageButton, BorderLayout.NORTH);
messageButton.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
JOptionPane.showMessageDialog(Audio.this, "The Message");
}
});
this.pack();
setVisible(true);
}

public static void main(String args[])
{
new Audio();
}
}

private void playSound() {
try{
FileInputStream fileau = new FileInputStream(new File("filename.wav")); //filename.wav是带路径的.绝对或者相对
AudioStream as = new AudioStream(fileau);
AudioPlayer.player.start(as);
}catch (Exception e){
}
}
然后在弹出JOptionPane之前调用这个方法.
