Good day,

I’m new FMOD and this is my first time actually using it. At the moment I’ve created a class with functions to play sound and load sounds etc…

Yet I’m getting thrown a fmod result error 30, an invalid object handle was used.

May I know what’s happening? Thanks!!

Error 30 is `FMOD_ERR_INVALID_HANDLE`, what exactly is returning the error?
