Hi,

There is the full stack from Unity 5.6.1f1 and Wwise 2016.2.2. We are facing the exact same issue since months and it occurs really often after hitting stop in the editor.

We're experiencing the same thing; frequent crashes when using the stop button in editor. We're using Unity 5.6.1p1 and Wwise v2016.2.3.

And the issue is present since december, still without any official answer : https://www.audiokinetic.com/qa/2973/unity-play-editor-wwise-crash-hitting-button-akterminator?show=2973#q2973

---

For us the issue was that on the scene that will be loaded first the WwiseGlobal is not on the root of the scene but on a parent (in order to organize stuff). Because of that DontDestroyOnLoad won't be effective, and when loading a new scene the previous wwiseglobal will be destroyed. This caused the crash. So removing it from being under a parent solved the issue.

Answer 2

Not sure if this will help with your issue, but for us it turned out that there was a second AkInitializer being created sometimes when the editor was exiting. I added a breakpoint in AkInitializer.Initialise() and saw that we had a lazy initiializer which was recreating our AudioManager object  within an OnDisable() method of a MonoBehaviour. According to Audiokinetic such a call-stack can be indicative of having two such objects.

Also double check that you're either using the WwiseGlobal game object or creating your own AkInitializer and not both.

Answer 3

Ok, I found a fix for this crash!

Add this in AKTerminator.cs:

    void OnEnable()
    {       
        //The sound engine was not terminated normally.  Make this instance the one that will manage termination.
        //This happen when Unity resets everything when a script changes.
        if (ms_Instance == null && AkSoundEngine.IsInitialized())
        {
            ms_Instance = this;
        }
    }
