Assertion failure in initialization on Mac OSX — minimal program included

Question

Hi, I'm evaluating Wwise for use in a new indie game project, but it consistently crashes on initialization. What am I doing wrong?

My Code:

#include <iostream>

#include <AK/SoundEngine/Common/AkMemoryMgr.h>
#include <AK/SoundEngine/Common/AkModule.h>
#include <AK/SoundEngine/Common/AkSoundEngine.h>
#include <AK/SoundEngine/Common/IAkStreamMgr.h>
#include <AK/MusicEngine/Common/AkMusicEngine.h>
#include <AK/Tools/Common/AkPlatformFuncs.h>
#include <AK/IBytes.h>

#ifndef AK_OPTIMIZED
#include <AK/Comm/AkCommunication.h>
#endif

#include <AkFilePackageLowLevelIOBlocking.h>

namespace AK
{
    void * AllocHook(size_t in_size)
    {
        void *ptr = malloc(in_size);
        std::cout << "Allocate " << in_size << " bytes @ " << ptr << "\n";
        return ptr;
    }

    void FreeHook(void * in_ptr)
    {
        std::cout << "Free " << in_ptr << "\n";
        free(in_ptr);
    }
}

static CAkFilePackageLowLevelIOBlocking g_lowlevel_io;

int main()
{
    // Init Memory
    std::cout << "Init Memory\n";
    AkMemSettings mem_settings;
    mem_settings.uMaxNumPools = 20;

    if (AK::MemoryMgr::Init(&mem_settings) != AK_Success) {
        return 1;
    }

    // Init Streaming
    std::cout << "Init Streaming\n";
    AkStreamMgrSettings stream_settings;
    AK::StreamMgr::GetDefaultSettings(stream_settings);

    if (!AK::StreamMgr::Create(stream_settings)) {
        return 1;
    }

    AkDeviceSettings device_settings;
    AK::StreamMgr::GetDefaultDeviceSettings(device_settings);

    if (g_lowlevel_io.Init(device_settings) != AK_Success) {
        return 1;
    }

    // Init Music
    std::cout << "Init Music\n";
    AkMusicSettings music_settings;
    AK::MusicEngine::GetDefaultInitSettings(music_settings);
    if (AK::MusicEngine::Init(&music_settings) != AK_Success) {
        return 1;
    }

    // Init Comms
    #ifndef AK_OPTIMIZED
    std::cout << "Init Comms\n";
    AkCommSettings comm_settings;
    AK::Comm::GetDefaultInitSettings(comm_settings);
    if (AK::Comm::Init(comm_settings) != AK_Success) {
        return 1;
    }
    #endif
}
