AudioInputStream不起作用

Question

我每次用户按下按钮时都会尝试播放.wav声音,但会抛出异常:

Exception in thread "Thread-0" java.lang.IllegalArgumentException: Invalid format
    at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.createStream(PulseAudioDataLine.java:142)
    at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.open(PulseAudioDataLine.java:99)
    at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.open(PulseAudioDataLine.java:283)
    at org.classpath.icedtea.pulseaudio.PulseAudioClip.open(PulseAudioClip.java:402)
    at org.classpath.icedtea.pulseaudio.PulseAudioClip.open(PulseAudioClip.java:453)
    at Uber.play(Uber.java:534)
    at Uber$5.run(Uber.java:340)
    at java.lang.Thread.run(Thread.java:724)

这是代码:

//Play Audio File
public void play(String file) throws LineUnavailableException, UnsupportedAudioFileException, IOException
{
    AudioInputStream inputStream = AudioSystem.getAudioInputStream(new File(file));
    Clip clip = AudioSystem.getClip();
    clip.open(inputStream);
    clip.start();
}

我设法让它运作起来.这是我使用的代码.请记住,我需要这个只是为了播放一个短的beep.wav声音.对于较长的声音文件似乎有些麻烦.让我知道它是否适合你们,如果你设法用这段代码播放更长的声音.

public void play(String file) throws LineUnavailableException, UnsupportedAudioFileException, IOException
    {

    try 
        {   
            AudioInputStream inputStream = AudioSystem.getAudioInputStream(this.getClass().getResource(file));
            AudioFormat format = inputStream.getFormat();
            DataLine.Info info = new DataLine.Info(Clip.class, format);
            Clip clip = (Clip)AudioSystem.getLine(info);
            clip.open(inputStream);
            clip.start();
        }

    catch (IOException | LineUnavailableException | UnsupportedAudioFileException e1)
        {
            e1.printStackTrace();
        }
    }
