Thank's for your help Frank,
I added your code to the one i'm using. still no sound.
here's the code i'm using :
Code :
// Converted from the WavFilePlay from the Teensy release:
// hardware/teensy/avr/libraries/Audio/examples/WavFilePlayer/WavFilePlayer.ino
//
// Simple RAW file player example for the prop shield to use the Analog DAC
// and prop shield amplifier to play mono sounds.
//
http://www.pjrc.com/teensy/gui/?info=AudioOutputAnalog
//
// On the prop shield, pin 6 selects the serial flash memory controller,
// and pin 5 enables the amplifier.
//
// This example code is in the public domain.
#include <Audio.h>
#include <Wire.h>
#include <SPI.h>
#include <SD.h>
#include <SerialFlash.h>
// GUItool: begin automatically generated code
AudioPlaySerialflashRaw playFlashRaw1; //xy=149,388
AudioMixer4 mixer1; //xy=445,386
AudioOutputAnalog dac1; //xy=591,379
AudioConnection patchCord1(playFlashRaw1, 0, mixer1, 0);
AudioConnection patchCord2(mixer1, dac1);
// GUItool: end automatically generated code
void setup() {
Serial.begin(9600);
// wait up to 3 seconds for the Serial device to become available
long unsigned debug_start = millis ();
while (!Serial && ((millis () - debug_start) <= 3000))
;
Serial.println ("Start prop shield RAW player");
// Enable the amplifier on the prop shield
dac1.analogReference(EXTERNAL); // much louder!
delay(50); // time for DAC voltage stable
Serial.println ("===> DAC1 Enabled");
pinMode(5, OUTPUT);
Serial.println ("PIN 5 SET AS OUTPUT");
digitalWrite(5, HIGH); // turn on the amplifier
delay(10); // allow time to wake up
Serial.println ("PIN 5 SET HIGH");
// Audio connections require memory to work. For more
// detailed information, see the MemoryAndCpuUsage example
AudioMemory(8);
// Set initial volume
mixer1.gain(0, 0.5f);
// uncomment these lines if you have a potentiometer or trimpot
// on the pin A1 to control the volume, and comment out the
// above line
// float vol = analogRead(VOLUME_POT);
// mixer1.gain(0, vol / 1024.0f);
// Start SerialFlash
if (!SerialFlash.begin(6)) {
while (1)
{
Serial.println ("Cannot access SPI Flash chip");
delay (1000);
}
}
}
void playFile(const char *filename)
{
Serial.print("Playing file: ");
Serial.println(filename);
// Start playing the file. This sketch continues to
// run while the file plays.
playFlashRaw1.play(filename);
// A brief delay for the library read RAW info
delay(5);
// Simply wait for the file to finish playing.
while (playFlashRaw1.isPlaying()) {
// uncomment these lines if you have a potentiometer or trimpot
// on the pin A1 to control the volume
// float vol = analogRead(VOLUME_POT);
// mixer1.gain(0, 1024 / 1024.0f);
}
}
void loop() {
playFile("BREAK.RAW"); // filenames are always uppercase 8.3 format
delay(500);
playFile("CLICK.RAW");
delay(1500);
}
