nokiaUI sound problem with MIDP 1.0 on Ngage

[iLya]

Hi Folks,
Im really stuck at this:
I have developped a game completely in MIDP 1.0. Now I want to have all these nice feats of the Nokia UI. I downloaded
the Nokia_7210_MIDP_SDK_v1_0
to compile and test my application.
FullScreen is working fine on my Ngage Phone and on all the emulators.
When I try to use Sound,( just started with playing a tone. (Sound play( freq, duration )))
it does work on the emulator, i can hear a nice beep. BUT it DOES NOT work on the Ngage phone. Though the play function is called, i cant hear the sound.
In other apps the sound does work so it is not because the Sound is Off.
Does anyone have an idea about whats going on ? Im implementing the sound just like its shown in the Tones Documentation from forum nokia:

This method is used to load a toneplayer
The TonePlayer is just an empty dummy
NokiaTonePlayer is a subClass of toneplayer which ueses the NOKIA UI .
and has a "Sound" variable, played via
snd.play(440,2000L);
*****
public static TonePlayer makeTonePlayer(){

TonePlayer player;

try {

// This statement throws an exception if no Nokia UI API available

Class.forName("com.nokia.mid.sound.Sound");

// If we get here, Nokia UI API is available, so we can safely
// create a player that uses it. But we use Class.forName rather
// than 'new' so that there is no link dependency.

Class clas = Class.forName("scim.bd.NokiaTonePlayer");

player = (TonePlayer)(clas.newInstance());

using = "Nokia";

}catch (Exception e) {

// If no Nokia UI API, then create a dummy tone player
player = new TonePlayer();

using = "default";

}

return player;
}
*****
In my game the nokia Player is actually used. ( using is always set to "Nokia" on both phone and emulators)
But still i hear no beep on the Phone.
Does anybody have an idea? or maybe a peace of functional code( I'm Using MIDP 1.0 )
big thx in advance

im using this now for NGage and tones (loaded from OTT files) and works fine even with multiple sounds,
check the sound.init() function, thats what i believe you are missing:


import java.io.*;
import com.nokia.mid.sound.*;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;

class SoundEffects
{
private static SoundEffects instance;
private MainCanvas pParent;

private Thread dThread; // Use a thread with the media player
private boolean disMTime, interrupted;
private String mtime;

private Sound sound = null;
int nloop = 1;
byte[] mBuf;

public SoundEffects(MainCanvas p, String file)
{
pParent = p;
createPlayer(file);
this.setVolume(pParent.master_volume);

}
void Stop()
{
sound.stop();
}
void close()
{
if( sound != null )
sound.release();
}
void setLoopCount(int loopcount)
{
nloop = loopcount;
}
void startGenericSound()
{
try
{
sound.init(mBuf, Sound.FORMAT_TONE);
this.setVolume(pParent.master_volume);
sound.play(1);
}
catch (Exception e) {e.printStackTrace();}

}

void setVolume(int volume)
{
volume = (((255<<8)/100)*volume);
sound.setGain(volume>>8);
//sound.setGain(255);
}

private void createPlayer( String filename )
{
try
{
int numbytes = 0;
InputStream tune = this.getClass().getResourceAsStream(filename);
while(tune.read()!=-1)
numbytes++;
tune = this.getClass().getResourceAsStream(filename);
mBuf = new byte[numbytes];
tune.read(mBuf,0,mBuf.length);
sound = new Sound(mBuf, Sound.FORMAT_TONE);

}
catch( Exception e )
{
e.printStackTrace();
}
}

public void ReplayIfStopped()
{
int state = sound.getState();
if( state == Sound.SOUND_STOPPED ||
state == Sound.SOUND_UNINITIALIZED )
startGenericSound();
}
}
