    series 60(Nokia 7650)'s sound capability

    I'm developing this game that utilizes Nokia's sound class. When testing i discovered that tones played in the emulator sound loud and clear, but when ported to the actual device(i used 7650) it sounded too soft that i have to actually put it beside my ear to hear the tones.

    Using getGain, to my surprise it displays a value of 0!!
    When i setGain to something else that is not 0, the tone refuse to play at all.

    I wouldn't want to use wav files that are so big, could somebody please help? My code is as below

    -----------------------------------------------------------------------------------

    import javax.microedition.midlet.*;
    import javax.microedition.lcdui.*;

    import com.nokia.mid.sound.*;

    public class TestCanvas extends Canvas
    {

    Sound sound;
    byte[] music = {
    (byte)0x02, (byte)0x4a, (byte)0x3a, (byte)0x40,
    (byte)0x04, (byte)0x00, (byte)0x1d, (byte)0x1c,
    (byte)0x82, (byte)0x2c, (byte)0x2a, (byte)0xc3,
    (byte)0x0c, (byte)0x35, (byte)0x04, (byte)0x91,
    (byte)0x69, (byte)0x18, (byte)0x20, (byte)0xd4,
    (byte)0x0c, (byte)0x30, (byte)0xd3, (byte)0x08,
    (byte)0xa0, (byte)0x00
    };


    TestCanvas()
    {
    sound = new Sound(music, Sound.FORMAT_TONE);
    sound.setGain(128);
    }

    public void paint(Graphics g)
    {
    g.setColor(0,0,0);
    g.fillRect(0,0,getWidth(), getHeight());
    g.setColor(255, 255, 255);
    g.drawString("gain is " + sound.getGain(), getWidth()/2, getHeight()/2, Graphics.TOP|Graphics.LEFT);
    }

    public void keyPressed(int key)
    {

    if(key == Canvas.KEY_NUM0)
    sound.setGain(sound.getGain() + 1);
    else if(key == Canvas.KEY_NUM1)
    sound.setGain(sound.getGain() + 2);
    else if(key == Canvas.KEY_NUM2)
    sound.setGain(sound.getGain() + 5);
    else
    sound.play(1);
    repaint();
    }

    }
