Hi I've been struggling to get any output from my computer using OpenAL. Granted I have a dodgy 24 bit soundcard but I can't even get output through my internal speaker. This is my source:

Code:

#define clickSound 1

{

    alutInit(&argc, argv);

    alListenerfv(AL_POSITION,listenerPos);

    alListenerfv(AL_VELOCITY,listenerVel);

    alListenerfv(AL_ORIENTATION,listenerOri);

    alGetError(); // clear any error messages

    // Generate buffers, or else no sound will happen!

    alGenBuffers(NUM_BUFFERS, buffer);

    if(alGetError() != AL_NO_ERROR) 

    {

        printf("- Error creating buffers !!\n");

        exit(1);

    }

    else

    {

        printf("init() - No errors yet.");

    }

alutLoadWAVFile("sound/click.wav",&format,&data,&size,&freq);

    alBufferData(buffer[clickSound],format,data,size,freq);

    alutUnloadWAV(format,data,size,freq);

    alGetError(); /* clear error */

    alGenSources(NUM_SOURCES, source);

    if(alGetError() != AL_NO_ERROR) 

    {

        printf("- Error creating sources !!\n");

        exit(2);

    }

    else

    {

        printf("init - no errors after alGenSources\n");

    }

    alSourcef(source[clickSound],AL_PITCH,1.0f);

    alSourcef(source[clickSound],AL_GAIN,1.0f);

    alSourcefv(source[clickSound],AL_POSITION,sourcePos);

    alSourcefv(source[clickSound],AL_VELOCITY,sourceVel);

    alSourcei(source[clickSound],AL_BUFFER,buffer[clickSound]);

    alSourcei(source[clickSound],AL_LOOPING,AL_FALSE);

alSourcePlay(source[clickSound]);

I receive no error messages. Should i check for errors after i try to play the sound?

Thanks in advance

My bet is that alutLoadWAVFile is failing, since you're not checking whether it's succeeded...

I dunno what was happening before but after a bit of fiddling and updating OpenAL along with getting the new CoreAudio SDK i have sound!!!

I think it was the way i bundled the sounds.

Thanks
