Why won't this code play a converted wav2c hea

问题:

I used this converter wav2c to convert a .wav file to a C that I can put in a header file. I was able to put converted audio into the h file but the program where I reference it does not seem to be working correctly. The code compiles and uploads to the Arduino but no sound plays. I used the code here to implement the converted audio. I'm using an 8-ohm 0.25w speaker. I'm no programmer nor an expert at electronics so it's likely something dumb that I did wrong. Any help is much appreciated!

The code in the header file (minus the hundreds of lines of values for the audio)

#ifndef _HEADERFILE_H    // Put these two lines at the top of your file.
#define _HEADERFILE_H    // (Use a suitable name, usually based on the file name.)


const int sounddata_length=10000;
//const int sounddata_sampleRate=8000;

const unsigned char sounddata_data[] PROGMEM = {
  15,1,49,0,150,0,138,0,219,255,133,0,176,0,15,1,210,254,16,1,197,255,65,0,9,0,227,0,127,254,87,0,175,1,61,254,132,1,135,255,21,1,72,0,104,1,172,0,122,0,213,1,65,255,188,1,100,1,215,0,210,255,59,2,17,0,193,0,200,2,207,255,203,0,65,1,17,1,169,255,121,2,112,0,193,255,65,255,252,255,232,0,101,255,88,2,4,0,26,255,

//Several hundred lines more of these numbers for the audio

105,108,101,45,49,46,48,46,50,52,41,0,105,100,51,32,42,0,0,0,73,68,51,3,
  0,0,0,0,0,31,84,88,88,88,0,0,0,21,0,0,0,83,111,102,116,119,97,114,101,0,76,97,118,102,53,50,46,57,51,46,48,0,};

#endif // _HEADERFILE_H    // Put this line at the end of your file.

Here is the code that I used from the Arduino Playground page to play the audio from the header file

    // Disable playback per-sample interrupt.
    TIMSK1 &= ~_BV(OCIE1A);

    // Disable the per-sample timer completely.
    TCCR1B &= ~_BV(CS10);

    // Disable the PWM timer.
    TCCR2B &= ~_BV(CS10);

    digitalWrite(speakerPin, LOW);
}
