Overview

The start() implementation in IOAudioDevice starts by calling start() on its superclass. It then calls initHardware() which the subclass should override to properly initialize itself and the hardware. If that call succeeds, it sets up power management if the family is supposed to manage power (checking the familyManagePower variable). Then finally it calls registerService() to make the IOAudioDevice visible in the IORegistry.
