第二次播放相同音频时格式不受支持的流

Question

[此类在第一次接收InputStream时就播放。尽管它第一次运行良好，但第二次它播放相同的流时却收到此异常。方法接收的任何InputStream均为.wav格式。

javax.sound.sampled.UnsupportedAudioFileException: Stream of unsupported format

我不确定以前使用该格式时会突然不被支持。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

Answer 1

如果您改为将文件位置的字符串发送到方法并在其中创建输入流，则它将起作用。
