I was able to get the Oculus Spatializer working on the GearVR with FMOD Support’s help and edited the post above to reflect this. I posted a rough outline of the process over on the Oculus forums to try and help Bino and anyone else in the Jam get it up and running as quickly as possible. If you are in the Mobile VR Jam and reading this while researching how to get the Oculus Spatializer working, the only option within UE4 at this time is to get FMOD up and running and deploying to Android successfully, which requires contacting FMOD Support. If you have a question about my process for getting it to work, reach out through a PM or post it here and I will answer if I am able.
