public static void main(String a[]) throws Exception{
    CaptureDeviceInfo di = null;
    Player p = null;
    Vector deviceList = CaptureDeviceManager.getDeviceList(new AudioFormat("linear", 44100, 16, 2));

    if (deviceList.size() > 0){
            di = (CaptureDeviceInfo)deviceList.firstElement();
            System.out.println((di.getLocator()).toExternalForm());
    }else{
            System.out.println("Exiting");
            System.exit(-1);
    }

    try{
            p = Manager.createPlayer(di.getLocator());
    }catch (IOException e){
            System.out.println(e);
    }catch (NoPlayerException e) {
        System.out.println(e);
    }
    System.out.println("Playing Started");
    p.start();
}
