ABSTRACT:
A computer system is provided with a device driver for adaptively operating a number of audio peripherals through a pair of digital audio controller and analog audio interface, in accordance with the audio functions supported by the analog audio interface, including for at least one audio function, the kind of support being provided. The analog audio interface includes one or more control registers for storing a number of functional indicators to indicate the audio functions supported, and for the at least one audio function, the support kind. The analog audio interface further includes a number of control registers for storing control information for modifying the behavior of the supported audio functions. These control information include a number enabling/disabling indicators and a number of power management indicators to allow the device driver to selectively enable/disable certain ones of the audio functions, as well as selectively power up and down certain ones of a number of independently powered components of the audio analog interface.
