Abstract
Systems and methods for controlling the capabilities of an High Definition Audio (HDA) system, wherein the system determines whether an optional component such as a plug-in card is connected to the system and then configures itself in a baseline configuration if the optional component is not connected or configures itself in a different, alternative configuration if the optional component is connected. In one embodiment, a codec of the system includes a programmable processor configured to read configuration authorization information and also read configuration information from the optional component if it is connected to the system. The processor also controls the configuration of the HDA system and the operation of the codec based on the authorization and configuration information. The system can thereby provide different features and functionality using the same hardware.
