I just use the AmbientDemo which is contained in the Wwise-Unreal Demo, and it works well in the Editor, but when I make a Windows-64bit application. The AmbientDemo does not work，I found that if I cancel the attenuation property of this audio in the Position tab, it would work again in the windows-64bit application,I guess it may be that I have missed something in that application,but i do not know how to do. Does any one help me?The Unreal-Version is 4.20
