PS-Set is a Power State field which defines the current power setting of the referenced node. Since this
node is an Audio Function Group node, the actual power state is this setting. Setting this field to the D3

1b
Power State Settings Reset (PS-SettingsRe-
set): This bit is set to ‘1’b when, during any type
of reset or low power state transition, the settings
that were changed from the defaults, either by
software or hardware, have been reset back to
their default state. When these settings have not
been reset, this is reported as ‘0’b. This bit is
always a ‘1’b following a POR condition. For
more information, see “Power State Settings

1b
Power State Clock Stop OK (PS-ClkStopOK):
This bit is set to a ‘1’b when the codec is capable
of continuing proper operation even when the
HD Audio Bus BITCLK has been stopped. This
bit is valid for the Audio Function Group node
and not the device widgets.

0b
Power State Error (PS-Error): This bit is not
supported and will always return ‘0’b when read.
The power state requested by software will
always be possible following a reasonable time
required to execute the power state transition.
There are no dependencies unknown to software
between nodes that would inhibit transitioning to
the requested power state.

Power State Actual (PS-Act): This field indi-
cates the actual power state of the referenced
node. The default state is D3.

Power State Set (PS-Set): Writes to these bits
set the Audio Function Group to the Power State
as described below:
PSS = ’0000’b; D0 - Fully on.
PSS = ‘0001’b; D1 - Not Supported
PSS = ‘0010’b; D2 - Not Supported
PSS = ‘0011’b; D3 - Allows for lowest possible
power consumption under software control. See
more information.
PSS = ‘0100’b; D4 - Not Supported
