OpenAL problem

Hey, I followed the tutorials on OpenAL and I've got it to work but for some reason after recompiling once, it stopped working. I have no idea why, I've searched the code many times and didn't find anything wrong. Maybe you guys can help me.

#include <conio.h>
#include <stdlib.h>
#include <al.h>
#include <alc.h>
#include <alut.h>
#include <stdio.h>

// Maximum data buffers we will need.
#define NUM_BUFFERS 2

// Maximum emissions we will need.
#define NUM_SOURCES 2

// These index the buffers and sources.
#define WALK   0
#define MAIN   1

    

// Buffers hold sound data.
ALuint Buffers[NUM_BUFFERS];

// Sources are points of emitting sound.
ALuint Sources[NUM_SOURCES];

// Position of the source sounds.
ALfloat SourcePos[NUM_SOURCES][2];

// Velocity of the source sounds.
ALfloat SourceVel[NUM_SOURCES][2];


// Position of the listener.
ALfloat ListenerPos[] = { 0.0, 0.0, 0.0 };

// Velocity of the listener.
ALfloat ListenerVel[] = { 0.0, 0.0, 0.0 };

// Orientation of the listener. (first 3 elements are "at", second 3 are "up")
ALfloat ListenerOri[] = { 0.0, 0.0, -1.0, 0.0, 1.0, 0.0 };


ALboolean LoadALData()
{
  // Variables to load into.

  ALenum format;
  ALsizei size;
  ALvoid* data;
  ALsizei freq;
  ALboolean loop;

	// Load wav data into a buffer.
   alGenBuffers(NUM_BUFFERS, Buffers);

  if (alGetError() != AL_NO_ERROR)
	{
 printf("ERROR 10: in loading wave files into buffer\n");
    return AL_FALSE;
	}

  alutLoadWAVFile("Data/foot.wav", &format, &data, &size, &freq, &loop);
  alBufferData(Buffers[WALK], format, data, size, freq);
  alutUnloadWAV(format, data, size, freq);

	alutLoadWAVFile("Data/main.wav", &format, &data, &size, &freq, &loop);
  alBufferData(Buffers[MAIN], format, data, size, freq);
  alutUnloadWAV(format, data, size, freq);

	// Bind buffers into audio sources.

  alGenSources(NUM_SOURCES, Sources);

  if (alGetError() != AL_NO_ERROR)
	{
 printf("ERROR 11: in binding buffers to audio sources\n");
    return AL_FALSE;
	}

  alSourcei (Sources[WALK], AL_BUFFER,  Buffers[WALK] );
  alSourcef (Sources[WALK], AL_PITCH,  1.0       );
  alSourcef (Sources[WALK], AL_GAIN,   1.0       );
  alSourcefv(Sources[WALK], AL_POSITION, SourcePos[WALK]);
  alSourcefv(Sources[WALK], AL_VELOCITY, SourceVel[WALK]);
  alSourcei (Sources[WALK], AL_LOOPING, AL_TRUE     );

	alSourcei (Sources[MAIN], AL_BUFFER,  Buffers[MAIN] );
  alSourcef (Sources[MAIN], AL_PITCH,  1.0       );
  alSourcef (Sources[MAIN], AL_GAIN,   1.0       );
  alSourcefv(Sources[MAIN], AL_POSITION, SourcePos[MAIN]);
  alSourcefv(Sources[MAIN], AL_VELOCITY, SourceVel[MAIN]);
  alSourcei (Sources[MAIN], AL_LOOPING, AL_TRUE     );

  // Do another error check and return.

  if( alGetError() != AL_NO_ERROR)
    return AL_FALSE;

  return AL_TRUE;

};

void SetListenerValues()
{
  alListenerfv(AL_POSITION,  ListenerPos);
  alListenerfv(AL_VELOCITY,  ListenerVel);
  alListenerfv(AL_ORIENTATION, ListenerOri);
};

void KillALData()
{
  alDeleteBuffers(NUM_BUFFERS, &Buffers[0]);
  alDeleteSources(NUM_SOURCES, &Sources[0]);
  alutExit();
};

// I add this to my Main function
/Initialize OpenAL and clear the error bit.
  alutInit(NULL, 0);
	alGetError();

	// Load the wav data.
  if (LoadALData() == AL_FALSE)
	{
 printf("FAILED LOADING DATA \n");
    return -1;
	};

SetListenerValues();

alSourcePlay(Sources[WALK]);//Footsteps sound
alSourcePlay(Sources[MAIN]);

Thanks

Check error after GenSource.

I am having the same problem and I do not see any errors being reported by alGetError().

Have you had any resolution on this cleves?

There is another thread with the same issue:
