How to get audio to work with CV1 headphones?

Hello,

Just a quick question; how do I get the audio in my unity project to work with the CV1 headphones? I made sure that I'm building in Unity 5.4 and I've imported the Oculus Audio SDK. I then went into Edit/ProjectSettings/Audio and made sure the spatializer is set to OculusSpatializer, yet when I make a build I do not hear anything through the CV1 headphones. Have I missed a step?

Thanks
