using Wave Shield for audio output

I have made a series of sensors that when triggered should play a specific audio file. Is there any reason that I would only be able to use three different audio files? I am hoping that I can use five but it seems to only be working with three. Code included below.

#include <SD.h>
#include <FatReader.h>
#include <SdReader.h>
#include <avr/pgmspace.h>
#include "WaveUtil.h"
#include "WaveHC.h"

SdReader card;    // This object holds the information for the card
FatVolume vol;    // This holds the information for the partition on the card
FatReader root;   // This holds the information for the filesystem on the card
FatReader f;      // This holds the information for the file we're play

WaveHC wave;      // This is the only wave (audio) object, since we will only play one at a time


void setup()
{
  Serial.begin(9600);  //Setup Serial

  pinMode(14, INPUT);      //Assigns analog pins 0-4 as sensor inputs
  pinMode(15, INPUT);
  pinMode(16, INPUT);
  pinMode(17, INPUT);
  pinMode(18, INPUT);
  pinMode(19, INPUT);       
  pinMode(6, OUTPUT);       //Assigns digital pin 6 as output 
  pinMode(7, OUTPUT);       //Assigns analog pin 7 as output for motor  
  pinMode(8, OUTPUT);       //Assigns digital pin 8 as output for LED cluster 1
  pinMode(9, OUTPUT);       //Assigns digital pin 9 as output for LED cluster 2
  // Set the output pins for the DAC control. This pins are defined in the library
  pinMode(2, OUTPUT);
  pinMode(3, OUTPUT);
  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
  pinMode(10, OUTPUT);  

  if (!card.init()) {         //play with 8 MHz spi (default faster!)  
    putstring_nl("Card init. failed!");  // Something went wrong, lets print out why
    sdErrorCheck();
    //    while(1);                            // then 'halt' - do nothing!
  }

  // enable optimize read - some cards may timeout. Disable if you're having problems
  //  card.partialBlockRead(true);

  // Now we will look for a FAT partition!
  uint8_t part;
  for (part = 0; part < 5; part++) {     // we have up to 5 slots to look in
    if (vol.init(card, part)) 
      break;                             // we found one, lets bail
  }
  if (part == 5) {                       // if we ended up not finding one  :(
    putstring_nl("No valid FAT partition!");
    sdErrorCheck();      // Something went wrong, lets print out why
    //    while(1);                            // then 'halt' - do nothing!
  }

  // Lets tell the user about what we found
  putstring("Using partition ");
  Serial.print(part, DEC);
  putstring(", type is FAT");
  Serial.println(vol.fatType(),DEC);     // FAT16 or FAT32?

  // Try to open the root directory
  if (!root.openRoot(vol)) {
    putstring_nl("Can't open root dir!"); // Something went wrong,
    //   while(1);                             // then 'halt' - do nothing!
  }

  // Whew! We got past the tough parts.
  putstring_nl("Ready!");
}

void sdErrorCheck(void)
{
  if (!card.errorCode())
    putstring("\n\rSD I/O error: ");
  Serial.print(card.errorCode(), HEX);

  Serial.println(card.errorData(), HEX);

  // ok time to play! start playback
  wave.play();

Hi there,

It's difficult to fix this without the original code and the five sound files.

If you still have the problem I'm happy to help, but uploading the sound files and original code are essential. What were the error messages you were receiving (if any?)

Cheers,
Johan

You only call three audio files - two are called twice.
cat.wav
help.wav
ghost.wav
help.wav
ghost.wav

Given that, how do you know all 5 don't work?

Do you have pulldown on inputs so they do not float?
