Unity and Xbox One Build Wwise: APU heap has already been allocated.

Question

I am receiving this error messages after deploying an Xbox One Push Build;

Build crashes as soon as it starts to initialize Wwise plugin.

Wwise: APU heap has already been allocated.

We're also getting the exact same issue. Wwise works fine on other platforms, only Xbox is having this problem.

Unity 2018.2.17f1
Wwise 2018.1.3.6784

So, not sure if it will help someone in the future or not, but for us it was Unity's default sound engine that was not disabled in the project settings / audio section (you have to check the 'disable' check box)
