Could you please post the definition of FMOD_RESULT. Its possible 
that the create sound function returns it on stack and not inside 
a register. This is usually the case if FMOD_RESULT is defined as 
a struct in C/C++. But its hard to say. In your case I would 
actually look at the disassembly and step through it to see where 
its going wrong and messing up the stack.
