SceAudio3d/HRTF on PS4 using UE4

Question

Is libSceAudio3d enabled by default with the UE4 plugin?  If not, what steps are necessary to get it enabled?

It's pretty clear that HRTF is not working in our game, and our log output appears to corroborate it:
>AK Error: Could not find plugin dynamic library SceAudio3d

I've been digging around and it seems like SceAudio3dSink needs to enabled and registered, but it doesn't appear to be registered by default (nor even included as part of the integration process for UE4).  Am I on the right track here, or there is something else we're missing/doing wrong?

Thanks,

Jared

We were running into the same issue as well. We were able to patch around the SceAudio3d prx not loading by making sure the "/app0/prx" folder was included in initSettings.szPluginDLLPath and that the SceAudio3d.prx file got coped into <GameName>/Build/PS4/prx.

#if PLATFORM_PS4
    FString PluginDLLPath(TEXT("/app0/prx/"));
#ifndef AK_SUPPORT_WCHAR
    AkOSChar * pszPluginDLLPath = TCHAR_TO_ANSI(*PluginDLLPath);
#else
    AkOSChar * pszPluginDLLPath = 0;
    CONVERT_WIDE_TO_OSCHAR(*PluginDLLPath, pszPluginDLLPath);
#endif
    initSettings.szPluginDLLPath = pszPluginDLLPath;
#endif

But then wwise still doesn't appear to open the 3d audio port like it does when you run the 3d audio sample from the SDK PS4 SDK (ORBIS SDKs\4.000\target\samples\sample_code\audio_video\api_audio3d\).

Rain 3d audio console output:

By comparison, our game's 3d audio console output:

23:35:15    [audiod/a3d] event.cc:187 - --> SceAudiodA3dEventWorkModeParam(4 0)
23:35:15    [audiod/a3d] morpheus.cc:561 - sceAudiodA3dMorpheusNotify, bAttached=1 bLegacyMode=0

23:35:15    [audiod/a3d] morpheus.cc:321 - Setting up Morpheus for Native mode

I can get the logging I would expect if I manualy open the 3d audio port:

#if PLATFORM_PS4
    {
        // Load audio3d Module
        int32 Ret = sceSysmoduleLoadModule(SCE_SYSMODULE_AUDIO_3D);
        checkf(Ret == SCE_OK, TEXT("sceSysmoduleLoadModule(SCE_SYSMODULE_AUDIO_3D) failed: 0x%x\n"), Ret);
        // Initialize Audio 3D
        Ret = sceAudio3dInitialize(0);
        checkf(Ret == SCE_OK, TEXT("sceAudio3dInitialize failed: 0x%x\n"), Ret);
    }

    SceAudio3dOpenParameters sParameters;

    sceAudio3dGetDefaultOpenParameters(&sParameters);
    sParameters.uiGranularity = 1024;
    sParameters.uiMaxObjects = 32;
    sParameters.uiQueueDepth = 1;

    SceAudio3dPortId uiPort;
    int iRet = sceAudio3dPortOpen(SCE_USER_SERVICE_USER_ID_SYSTEM, &sParameters, &uiPort);
    if (iRet) {
        UE_LOG(LogInit, Warning, TEXT("sceAudio3dPortOpen() failed: 0x%x"), iRet);
    }
#endif

We have the "SCE Audio 3d bed" setup in our wwise project config, but no dice so far.
