Advice with renaming DLL is pointless for modern Creative cards. Some post X-Fi cards support both hardware and software OpenAL (like Z, ZxR), but AE-5, G-6, etc. don't. It'll result in error "Native Device not default" in logs instead. Also, it's necessary to switch installed DLLs in most cases (can be checked in OpenAL tools).
