FMOD Error 51 Error Initializing Output Device on iOS

We’re calling m_fmod_studio->initialize(512, FMOD_STUDIO_INIT_NORMAL, FMOD_INIT_NORMAL|FMOD_INIT_3D_RIGHTHANDED, 0) to intialize FMOD. This seems to work fine in every instance that I’ve tried personally on Win/Mac/Linux/iOS/Android however when deployed in the field…and on iOS only, I have many users that are getting an FMOD error 51 - Error initializing output device.

I’ve seen several other threads around the internet about this happening when another app is using FMOD and both are trying to do profiling or LiveUpdate but as you can see from my initialization call, I’m not trying to do that.

Has anyone else seen this?
