Apple defines Core Audio as having three software layers: (1) Applications-level Services, (2) Hardware Abstraction Layer (HAL), and (3) Drivers (kernel extensions) that interface directly with hardware devices.
Developers who claim they are bypassing Core Audio in OS X seem be communicating with the driver of the selected audio device through Core Audio's Hardware Abstraction Layer rather than through the Applications-level Services Layer. This is still part of Core Audio.
It would be more accurate to say they are bypassing some of Core Audio's higher level services.
