Hi, I've Purchased WTV020-SD.


I use a Microsd 2GB, in this I've copied ad4 files audio.
I used this sketch:

/*
Example: Control a WTV020-SD-16P module to play voices from an Arduino board.
Created by Diego J. Arevalo, August 6th, 2012.
Released into the public domain.
*/

#include <Wtv020sd16p.h>

int resetPin = 2;  // The pin number of the reset pin.
int clockPin = 3;  // The pin number of the clock pin.
int dataPin = 4;  // The pin number of the data pin.
int busyPin = 5;  // The pin number of the busy pin.

/*
Create an instance of the Wtv020sd16p class.
1st parameter: Reset pin number.
2nd parameter: Clock pin number.
3rd parameter: Data pin number.
4th parameter: Busy pin number.
*/
Wtv020sd16p wtv020sd16p(resetPin,clockPin,dataPin,busyPin);

void setup() {
 //Initializes the module.
 wtv020sd16p.reset();
}

void loop() {
 //Plays synchronously an audio file. Busy pin is used for this method.
 wtv020sd16p.playVoice(0);
 //Plays asynchronously an audio file.
 wtv020sd16p.asyncPlayVoice(1);
 //Plays audio file number 1 during 2 seconds.
 delay(5000);
 //Pauses audio file number 1 during 2 seconds.  
 wtv020sd16p.pauseVoice();
 delay(5000);
 //Resumes audio file number 1 during 2 seconds.
 wtv020sd16p.pauseVoice();
 delay(5000);  
 //Stops current audio file playing.
 wtv020sd16p.stopVoice();
 //Plays synchronously an audio file. Busy pin is used for this method.  
 wtv020sd16p.asyncPlayVoice(2);
 delay(2000);  
 //Mutes audio file number 2 during 2 seconds.
 wtv020sd16p.mute();
 delay(2000);
 //Unmutes audio file number 2 during 2 seconds.
 wtv020sd16p.unmute();
 delay(2000);    
 //Stops current audio file playing.
 wtv020sd16p.stopVoice();
}

The problem is that can not hear anything!
Can you help me please? I'm going crazy.
Thanks in advance.

I did various test and now in the speaker feel different whistles.
I am waiting for answers to the problem
