Ah, so I seem to have solved the issue, though I’m still not entirely sure what the issue was!

On Mobile, the `AmbienceController` GameObject is nested inside the prefab that it corresponds to. Users use this parent prefab to access the functionality to call our ambience playing functionality, and the parameter triggering functionality.  
In our Standalone app, it followed a similar format, where it was nested inside the prefab that allows users to preview ambiences and parameter changes.  
I moved the `AmbienceController` GameObject out of this preview prefab, and the appropriate storm sounds when our Weather parameter is set to 1 are now audible!

Thanks so much for your help Jeff. I’m unsure if this is helpful in any way, especially as you were not able to reproduce our issue on your end. To anyone else that might be experiencing something similar, definitely try to play around with your hierarchy, as it may solve your issue!

I _am_ also getting some strange behaviour from adding `StudioGlobalParameterTrigger` components at runtime, though this does not occur on Mobile editor. A number of `NullReferenceExceptions` appear at the same time. I will have to do some testing to see if this occurs in a build, but I believe it is something to do with the Inspector slider specifically. The errors do not occur if the `AmbienceController` GameObject is not open in the Inspector. We can definitely live with this issue!
