Re: setup 3d audio

I tested with a mono sound but it is too noisy,
i find a tutorial but they use alut to load files and its depreciated...

maybe the problem is when i init openAL? or when i load the file ? with
libsndfile

/**********************************************************/
init openal:
ASS_Device* ASS_InitDevice(ASSenum device_type)
{
    ASS_Device* d=NULL;
    list_memory_allocated=NULL;

    if (!(d=(ASS_Device*)malloc(sizeof(*d)))) return NULL;

    ASS_AddLast(&list_memory_allocated,(int)d,sizeof(*d));
    d->device=NULL;
    d->context=NULL;
    switch (device_type)
    {
    case ASS_DEFAULT_DEVICE:
        d->device=alcOpenDevice(NULL);
        break;
    case ASS_PULSEAUDIO_DEVICE:
        d->device=alcOpenDevice("PulseAudio Software");

        break;
        default:
        break;
    }
    if (!d->device) return NULL;

    d->context = alcCreateContext(d->device,NULL);
    if (!d->context) return NULL;

    if (!alcMakeContextCurrent(d->context))
    {
        ASS_FreeList(list_memory_allocated);
        return NULL;
    }

      is_multi_channel = (alIsExtensionPresent("AL_EXT_MCFORMATS") ==

      printf("Audio device info:\n------------------\n");
