I solved the problem by simply passing the parameter null into AudioSystem.getClip().

I don't know why this exception occured, I run this project before on Windows, and it worked... After on Linux and here, it didn't work.

I had the same problem and found this code to work:

File soundFile = new File("/home/usr/Desktop/d.wav");
AudioInputStream soundIn = AudioSystem.getAudioInputStream(soundFile);
AudioFormat format = soundIn.getFormat();
DataLine.Info info = new DataLine.Info(Clip.class, format);
Clip clip = (Clip)AudioSystem.getLine(info);
clip.open(soundIn);
clip.start();
while(clip.isRunning())
{
   Thread.yield();
}

The key is in soundIn.getFormat(). To quote the docs:

Obtains the audio format of the sound data in this audio input stream.

The error message says that the input file format is wrong somehow.

If you gave us more information (file format, maybe where you got it, code that you use to open the file and how you configured the audio drivers), we might be able to help.

See this question for some code that you can try: How to play .wav files with java
