When building my Unreal 4.9.2 game with FMOD 1.06.10, I get this:

FMODUtils.cpp.obj : warning LNK4221: This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library

That doesn’t indicate an actual problem, but the warning message is annoying. The fix is to just remove FMODUtils.cpp since it is empty now.

We’ll do that for the next release.
