PS-Set is a PowerState field which defines the current power setting of the referenced node. Since this
node is of type other than an Audio Function Group node, the actual power state is a function of both this
setting and the PowerState setting of the Audio Function Group node under which this node was enumer-
ated (is controlled).
PS-Act is a PowerState field which indicates the actual power state of this node. Within the Audio Func-
tion Group node, this field will always be equal to the PS-Set field (modulo the time required to execute a
power state transition). Within this type of node, this field will be the lower power consuming state of either
a) the PS-Set field of the currently referenced node or b) the PS-Set field of the Audio Function Group
node under which the currently referenced node was enumerated (is controlled).

Power State Error (PS-Error): This bit is not
supported and will always return ‘0’b when read.
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
“D3 Lower Power State Support” on page 25
more information.
PSS = ‘0100’b; D4 - Not Supported
Reserved
H-Phone Enable (HPE) : This bit has no affect
on the output path. Per HD Audio spec, a ‘1’
enables a low impedance amplifier associated
with the output. When ‘0’, this bit disables a low
impedance amplifier associated with the output.
Output Enable (OUTE) : This bit has no affect on
the output path. Per HD Audio spec, a ‘1’
enables the output path of the Pin Widget. When
‘0’, the output path of the Pin Widget is shut off.
Input Enable (INE) : Set to ‘0’ since there is no
input path associated with the pin widget.
