In the Viking Village tutorial I’m stuck at the footsteps script. When I enter play mode I don’t hear my footsteps at all. And in the console window I’m getting this compiler error message many times:

_NotImplementedException: The method or operation is not implemented._  
_FMOD.Studio.EventInstance.setParameterValue (System.String v1, System.Int32 v2) (at Assets/Plugins/FMOD/src/Runtime/wrapper/fmod\_studio.cs:1345)_  
_Footsteps.PlayFootstepSound () (at Assets/Scripts/Footsteps.cs:196)_  
_Footsteps.Update () (at Assets/Scripts/Footsteps.cs:102)_

Everything in Fmod is working. I can play my Fmod footsteps while in Unity outside of play mode/in the editor by triggering the event in the Flyingrigidbody… But the footsteps aren’t happening in playmode. Any help is appreciated. Thanks.

FMOD 2.0 introduced a new Parameter API, we also added a new section to the Integration docs recently with information on major changes in the different versions.
