Unity FMOD 16 speakers audio output

Hi
I am trying to set up a 16-speaker system using MOTU hardware, and I’m using FMOD in Unity to play audio. In Unity, an audio source moves around the player in different directions, and I want to hear this spatial movement across my speaker array.
Currently, when the audio source moves around the player in a circle, for example, it does not sound like the sound is being distributed correctly across all speakers or going around the listener. The FMOD Preferences are set to ASIO. Any ideas what I am doing wrong or what I am missing in my set up? Thank you in advance
