The following method "sound" works on my PC and it sounds a beep. I am using java 1.5
and Jdeveopler 10.1.3.4 on Windows XP/SP2.
import javax.sound.sampled.*;
public void handleBeep(ReturnEvent returnEvent)
{
try {
sound(2000,150);
} catch (LineUnavailableException lue) {
System.out.println(lue);
}
}
public static void sound(int hz,int msecs) throws LineUnavailableException {
byte[] buf = new byte[msecs*8];
for (int i=0; i<buf.length; i++) {
double angle = i / (8000.0 / hz) * 2.0 * Math.PI;
buf[i] = (byte)(Math.sin(angle) * 80.0);
}
AudioFormat af = new AudioFormat(8000f,8,1,true,false);
SourceDataLine sdl = AudioSystem.getSourceDataLine(af);
sdl.open(af);
sdl.start();
sdl.write(buf,0,buf.length);
sdl.drain();
sdl.close();
}
and Jdeveopler 10.1.3.4 on Windows XP/SP2.
import javax.sound.sampled.*;
public void handleBeep(ReturnEvent returnEvent)
{
try {
sound(2000,150);

sdl.close();
}
Great, I have drive-by code snippets, drive-by flu shots, I think I'm set for life

I'm sorry but are you asking for help? If not, congratulations on getting your beep method to work. If you are asking for help, what is your question?
" No line matching interface SourceDataLine supporting format PCM_SIGNED 8000.0 Hz, 8 bit, mono, 1 bytes/frame, is supported." from Unix (Sun). Any thought ? Thanks.
