When some people talk about LLE, they really mean LLE audio. LLE stands for Low-Level Emulation, but a lot of people simply say LLE to refer to the DSP Emulator Engine (which is technically incorrect). The LLE on Thread option has been renamed in recent revisions due to this confusion.
Note, you need to either dump the necessary LLE files yourself, or just use the latest revision (which has its own DSP files) in order to use LLE audio at all.
