Im trying to see if i can produce a working openal console proj from "scratch". I can get the sample code to compile without errors but whenever i simply transfer the code to a blank project i can not produce any sounds. I recieve two warnings about the depricated alut functions but that is it. Would someone be kind enough to look at the code and tell me if i have done anything wrong?

#include <al/alut.h>  

#include <al/Framework.h>



#define WAV_FILE "smile.wav"


// Position of the source sound.

ALfloat SourcePos[] = { 0.0, 0.0, 0.0 };


// Velocity of the source sound.

ALfloat SourceVel[] = { 0.0, 0.0, 0.0 };



// 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")

// Also note that these should be units of '1'.

ALfloat ListenerOri[] = { 0.0, 0.0, -1.0,  0.0, 1.0, 0.0 };




int main()

{

	ALuint buffer;

	ALuint source;


	

	ALenum format;

	ALsizei size;

	ALvoid *data;

	ALsizei freq;

	ALCdevice *device = alcOpenDevice(NULL);

	

	if (device) 

	{

		ALCcontext *context = alcCreateContext(device,NULL);

		alcMakeContextCurrent(context);

	}

	alGetError(); // clear error code

	alGenBuffers(1, &buffer);

	if ((error = alGetError()) != AL_NO_ERROR)

	{

		return(-1);

	}

	// Load test.wav

	alutLoadWAVFile(WAV_FILE,&format,&data,&size,&freq,&loop);

	if ((error = alGetError()) != AL_NO_ERROR)

	{

		alDeleteBuffers(1, &buffer);

	}

	// Copy test.wav data into AL Buffer 0

	alBufferData(buffer,format,data,size,freq);

	alSourcefv(source, AL_POSITION, SourcePos);

	alSourcefv(source, AL_VELOCITY, SourceVel);

	alSourcei (source, AL_LOOPING,  loop     );

	

	

	if(alGetError() != AL_NO_ERROR)

		return(-6);




	// Attach buffer 0 to source

	alSourcei(source, AL_BUFFER, buffer);

	if ((error = alGetError()) != AL_NO_ERROR)

	{

	      return(-7);

	}


	alListenerfv(AL_POSITION,    ListenerPos);

	alListenerfv(AL_VELOCITY,    ListenerVel);

	alListenerfv(AL_ORIENTATION, ListenerOri);



	alSourcePlay(source); 


	// EXIT

	ALCcontext *Context=alcGetCurrentContext();

	ALCdevice *Device=alcGetContextsDevice(Context);

	alcMakeContextCurrent(NULL);

	alcDestroyContext(Context);

When you transfer the code to a blank project, are you setting it to link with the OpenAL libraries? Also, is "smile.wav" in the new project directory?

I believe i have set it to link to the openal lib otherwise i would get linker errors right? I have "alut.lib OpenAL32.lib" listed in the additional dependencies spot for the linker settings. and smile.wav is in the project directory (with the main.cpp file)

If you're using windows check any openal dlls are accessable (in the path or the same directory as the program)

alut.dll is in the directory but i dont have any openal dll files. also the program doesnt run without the alut.dll file so does that mean alut.dll is the only one it needs?

[animatedantmo]

OK i managed to get sound to work. I used a different OpenAL32.dll and that seemed to fix the problem.

Thanks for trying guys :)
