Systems and methods for controlling HDA system capabilities

A method implemented in an High Definition Audio (HDA) amplification system, the method comprising:

• determining whether an optional component is connected to the audio amplification system;
• configuring the audio amplification system in a baseline configuration, when the optional component is not connected to the audio amplification system, by enabling a baseline subset of a set of audio processing features and disabling one or more audio processing features outside the baseline subset;
• and
• configuring the audio amplification system in an alternative configuration, when the optional component is connected to the audio amplification system, by enabling an alternative subset of the set of audio processing features that is different from the baseline subset, wherein the alternative configuration is different from the baseline configuration, and wherein the alternative subset includes at least one of the audio processing features disabled in the baseline configuration;
• and
• wherein the at least one of the audio processing features disabled in the baseline configuration, and enabled in the alternative configuration, cannot be enabled unless the optional component is connected to the audio amplification system.

A method implemented in an High Definition Audio (HDA) amplification system, the method comprising:

• determining a set of authorized audio processing features, wherein the set of authorized audio processing features does not include every audio processing feature which the HDA amplification system is capable of providing;
• determining whether an optional component is connected to the HDA amplification system;
• determining a hardware configuration of the HDA amplification system based on whether the optional component is connected to the HDA amplification system;
• determining a set of available audio processing features based on the determined hardware configuration;
• and
• configuring the HDA amplification system to provide audio processing features that are included in both the set of authorized audio processing features and the set of available audio processing features.
