Hi,
Your issue is caused by a mismatch in bank build and bank import locations, causing your Unity project to not have access to up-to-date banks.
You’ve set your banks to be built to your Unity project directory, but you’ve also set the FMOD Unity Integration to use your FMOD Studio project’s path - meaning that while FMOD Unity is searching for banks in your Studio project’s ./Build folder, your banks are being built to your Unity project’s ./Assets/FMOD folder instead.
To fix this, you can either remove the “Built banks output directory” path from your Studio project’s preferences, causing Studio to build the banks to the project directory, or change your FMOD Unity Source Type to Single/Multiple Platform Build and specify ./Assets/FMOD as the build path.
The “FMOD Bank Sub Folder” specifies what subfolder to copy your .bank files to when you build your game, it should have no effect on importing your banks in the Unity editor.
Hope this helps!
