Have you added a Mobile platform to your FMOD Studio project and built the banks for the Mobile platform? The Mobile platform must also be using “Mobile” for its sub-output directory.

When building for Android our UE4 integration will copy the banks from the “Mobile” sub-output directory and the integration is hard-coded to use the “Mobile” sub-output directory at runtime.

Thanks for reporting this. We’re currently investigating several reports of this issue but it’s not affecting everyone. Can you tell us which specific version of FMOD you’re using, and which device(s) you’re seeing the issue on?

Thanks, we’ve been able to reproduce this now and are investigating. I’ll update this topic as soon as we have more information.

We’ve now been able to fix this crash. The fix will be included in our next release of the FMOD Studio UE4 integration.

In the meantime the fix has been pushed to GitHub ([https://github.com/fmod/ue4integration](https://github.com/fmod/ue4integration)), so if you’re comfortable using GitHub you can get the fix form there right away. It’s a simple change to `FMODStudio/Source/FMODStudio/Private/FMODStudioModule.cpp` - just grab the file from the appropriate branch at GitHub and replace the version from our integration package.

As an alternative, you should be able to work around the issue by setting the “Built bank file separation” setting in your FMOD Studio project to one of “Build metadata and assets to separate banks” or “Build metadata, non-streaming assets, and streaming assets to separate banks”.
