We found that in some iOS devices, our app will crashed sometimes when initializing FMOD. Here is the error log:  
name = SystemNotInitializedException  
reason = FMOD Studio initialization failed  
callstack =  
FMODUnity.SystemNotInitializedException…ctor (RESULT result, System.String location)  
FMODUnity.RuntimeManager.Initialiase (Boolean forceNoNetwork)  
FMODUnity.RuntimeManager.get\_Instance ()

FMOD Version: 1.09.06  
iPhone 6 iOS10.3.3

If you could send through a full log to [support@fmod.com](mailto:support@fmod.com), I can take a look at that.

Are you able to reproduce this?  
Any other information you have may be helpful as well.
