VRC.PC.Audio.1 - Oculus Audio submission fail

Hello!

After several rounds of technical review for a Rift game we're putting on the store we've successfully met all criteria but for one: VRC.PC.Audio.1

We are using UE4 + Fmod studio for this project. Oculus Audio plugin is enabled but we are not using it. As spatialization plug-in we use resonance. VRC.PC.Audio.2 regarding spatialization is approved.

On our UE Initial project settings we have set "Rift Audio" as the "Initial Output Driver Name". Is there other setting that we are missing in order to solve this issue?

Thank you!!!
