HI Andrew

For some reason, all the music and ambience events in the game stopped triggering. As in they do not show up in the FMOD profiler, but the other sounds do.  
I have tried:  
reassigning music to different banks  
changing routing in Mixer  
snapshot levels check  
path/prefab check  
all the refreshes  
removing banks entirely and rebuilding  
changing streaming/pre-load settings  
changing channel settins (automatic-\> stereo, etc)  
delete cache and reimport  
etc.

Tbh I don’t know which error is the culprit. (i am not a dev)

```auto
[FMOD] EventInstance::stop(0) returned ERR_INVALID_HANDLE for STUDIO_EVENTINSTANCE (0x0).
UnityEngine.Debug:LogError (object)
FMODUnity.RuntimeUtils:DebugLogError (string) (at Assets/Plugins/FMOD/src/RuntimeUtils.cs:594)
FMODUnity.RuntimeManager:ERROR_CALLBACK (intptr,FMOD.SYSTEM_CALLBACK_TYPE,intptr,intptr,intptr) (at Assets/Plugins/FMOD/src/RuntimeManager.cs:142)
FMOD.Studio.EventInstance:stop (FMOD.Studio.STOP_MODE) (at Assets/Plugins/FMOD/src/fmod_studio.cs:1377)

```

Any sugggestions as to what I should try next? (@jeff_fmod Do maybe you have some insight/advice on this please?)

SOLVED! It was an internal setup where events that were called before they were loaded were not played, and no error logged.
