GetSourcePlayPosition doesn't work in 2022.1.3

Question

I always get AK_NotInitialized when call GetSourcePlayPosition after upgrading to Wwise 2022.1.3.

Is it a known issue? Thanks.

Not work in 2022.1.3-2022.1.6
I guess it is caused by the inconsistency of SoundEngine。AK::SoundEngine is not instanced, So，return AK_NotInitialized.
But, can do as this:

//used by Cpp/Blueprint

int32 UAkGameplayStatics::GetSourcePlayPosition(UAkAudioEvent* AkEvent, int32 PlayingID)
{
    if (AkEvent) {
        return AkEvent->GetSourcePlayPosition(PlayingID);
    }
    return -1;
}

//expand UAkAudioEvent

int32 UAkAudioEvent::GetSourcePlayPosition(int32 PlayingID)
{
    SCOPED_AKAUDIO_EVENT_2(TEXT("UAkAudioEvent::PostEvent"));
    auto* AudioDevice = FAkAudioDevice::Get();
    if (UNLIKELY(!AudioDevice))
    {
        UE_LOG(LogAkAudio, Verbose, TEXT("Failed to post AkAudioEvent '%s' without an Audio Device."), *GetName());
        return AK_INVALID_PLAYING_ID;
    }

    if (UNLIKELY(!AudioDevice->IsInitialized()))
    {
        UE_LOG(LogAkAudio, Verbose, TEXT("Failed to post AkAudioEvent '%s' with the Sound Engine uninitialized."), *GetName());
        return AK_INVALID_PLAYING_ID;
    }

    auto* SoundEngine = IWwiseSoundEngineAPI::Get();
    if (UNLIKELY(!SoundEngine))
    {
        UE_LOG(LogAkAudio, Warning, TEXT("Failed to post AkAudioEvent '%s' without a Sound Engine."), *GetName());
        return AK_INVALID_PLAYING_ID;
    }

    auto* ExternalSourceManager = IWwiseExternalSourceManager::Get();
    if (UNLIKELY(!ExternalSourceManager))
    {
        UE_LOG(LogAkAudio, Warning, TEXT("Failed to post AkAudioEvent '%s' without the External Source Manager."), *GetName());
        return AK_INVALID_PLAYING_ID;
    }

    AkTimeMs CurrentPosition = 0;
    auto Result = SoundEngine->GetSourcePlayPosition(PlayingID, &CurrentPosition);
    if (Result == AK_Success)
    {
        return CurrentPosition;
    }
    else
    {
        GEngine->AddOnScreenDebugMessage(-1, 2.f, FColor::Red, TEXT("GetSourcePlayPosition FAILED!"), false);
        return -1;
    }
}
