The HD Audio specification defines power states, power state widgets, and power state verbs.
Power management is implemented at several levels. The Audio Function Group (AFG) , all con-
verter widgets, and all pin complexes support the power state verb F05/705. Converter widgets are
active in D0 and inactive in D1-D3.
The following table describes what functionality is active in each power state.
