当这个类收到一个输入流来播放它第一次工作时。第二次播放相同的流时，尽管第一次工作正常，但我还是得到了这个异常。该方法接收的任何输入流都采用.wav格式。
javax.sound.sampled.UnsupportedAudioFileException: Stream of unsupported format
我不确定以前工作时该格式如何突然不受支持。 这是代码。
package Megalo;
import java.io.BufferedInputStream;
import java.io.InputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.LineUnavailableException;
import javax.swing.JOptionPane;
public class Starter
{
private Clip clip;
public Starter()
{
try
{
clip = AudioSystem.getClip();
}
catch (LineUnavailableException e)
{
JOptionPane.showMessageDialog(null, "Error: Cannot find audio system");
e.printStackTrace();
}
}
public void activate(InputStream song)
{
BufferedInputStream audioSong= new BufferedInputStream(song);
try
{
clip.open(AudioSystem.getAudioInputStream(audioSong));
clip.start();
Thread.sleep((clip.getMicrosecondLength() / 1000) - 1);
clip.close();
}
catch (Exception e)
{
JOptionPane.showMessageDialog(null, e.toString());
e.printStackTrace();
}
}
}
这是堆栈跟踪

如果您将文件位置的字符串发送到该方法并在那里创建 inpustream，它将起作用。
