Using the following code example (a simple audio player), I hear clicks while
the audio file is playing. I tested it on different machines with sound cards
SB16, SB128 PCI using ALSA or kernel module sound. Other audio applications like
'sox' play the audiofiles well, so I don't think that my audio configuration is
wrong.

Usage of program: java AudioPlayer wav_file

/*
 * AudioPlayer.java
 */

import javax.sound.sampled.*;
import java.io.*;

public class AudioPlayer {
   
    AudioFileFormat affm;
    AudioFormat afm;
    SourceDataLine sdl;
    String filename;
    File f;
    AudioInputStream s;
    byte buf[];
    int length;
    
    /** Creates new AudioPlayer */
    public AudioPlayer(String filename) {
        this.filename = filename;
play(f);
    }

    public void play(File f) {

try {
            f=new File(filename);
            affm=AudioSystem.getAudioFileFormat(f);
s=AudioSystem.getAudioInputStream(f);
DataLine.Info info = new DataLine.Info(SourceDataLine.class,
affm.getFormat() );
            sdl = (SourceDataLine) AudioSystem.getLine(info);
length=(int)s.getFrameLength()* affm.getFormat().getFrameSize();
buf= new byte[length];
int read;
read=0;
while(read<length) {
read+=s.read(buf,read,length);
}
System.out.println("Read "+read+ " Bytes.");
sdl.open(affm.getFormat());
} catch (Exception e ) {
e.printStackTrace();
            System.exit(1);
        }
sdl.start();
sdl.write(buf,0,length);

    }
    
    public static void main( String args[] ) {
new AudioPlayer(args[0]);
    }
}

Thanks.
