Fmod + Steam Audio Unity Occlusion not working (FMOD Studio fails to load Steam Audio plugin (phonon.dll) – “No FMOD symbols found”)

Hi I’m integrating FMOD Studio and Steam Audio into my Unity project for the first time and running into a plugin loading issue. When I launch FMOD Studio (v2.02.28), I get this error in the terminal: “13:26:33 fmod_pluginfactory.cpp(580), PluginFactory::loadPlugin(): No FMOD symbols found in dynamic library ‘C:/Users/douty/Documents/FMOD Studio/Mannequin/Plugins/phonon.dll’
13:26:33 Error loading plugin C:/Users/douty/Documents/FMOD Studio/Mannequin/Plugins/phonon.dll: Error loading file.” Im quite new to Both Fmod and Steam Audio but have used them separately on a previous game project where they worked fine however now that im using both together they dont seem to want to cooperate. The main problem is that i can attach the Steam audio Spatializer and such and some things even work, however when i turn on “Simulation based Occlusion” The sound wont play in either Fmod or the Unity Scene but it does play in the event browser so im really confused to what the problem is. Ive been trouble shooting this for a couple days now and have yet to find an answer so any help would be much appreciated. Could there be a mismatch in plugin versions, or am I missing a step?

Thanks in advance!

This is because Studio will attempt to load all the libs it finds in the plugins directory, but the phonon.dll is Steams own lib which does not contain anything about FMOD which is why they include a phonon_fmod.dll. But that’s not really anything to worry about.

Are you able to connect the Studio Profiler to see if the event is spawning and starting? It may be that the event is being occluded or stopped from playing by something.
