Hello,  
I have a huge game project that is basically done and published but wanted to move from using Unity’s built in audio engine to FMOD engine. I have imported the Unity FMOD API to the project and run the setup. However, I can’t seem to write any code involving FMOD system. I didn’t encounter this problem in my previous project, but that project was small. I don’t know if this info is important, but we have our project in GitLab.

Hi,

Thank you for the information. What version of FMOD are you using? The issue may be that you are missing a reference to the `FMODUnity.asmdef`. A similar issue can be found here: [FMOD Unity "Missing directive or an assembly reference" - #4 by Connor\_FMOD](https://qa.fmod.com/t/fmod-unity-missing-directive-or-an-assembly-reference/21916/4).
