According to my Crashlytics reports, I’ve been getting crashes on Android due to a FMOD null pointer exception.
Here is the stack trace:

Hi,

This is an error with Unity’s audio system - the reason FMOD is showing up in the stack trace is that Unity’s audio system is based on an old version of FMOD. For assistance with your issue, you’ll want to post this on Unity’s forums.
