Power Management
Table 5 describes the active functionality in each power state.
The D3-default state is available for HD Audio compliance. The programmable values exposed via
vendor-specific settings are under the IDT Device Driver control for further power reduction.
The default power state for the Audio Function Group after reset is D3-default.
PC Beep may need to be active on power up, in which case the BIOS is responsible for enabling it
by setting AnalogBeepEn in the AFG AnaCtrl widget. The PC_BEEP input is routed directly to the
MONO_OUT, LINE_OUT and HP_OUT pins of the CODEC. Because the PC_BEEP input drive is
often a full scale digital signal, some resistive attenuation of the PC_BEEP input is recommended to
keep the beep tone within reasonable volume levels. The user should mute this input before using
any other mixer input because the PC Beep input can contribute noise to the lineout during normal
operation.
Analog PC-Beep is not supported during Link Reset.
Headphone Drivers
Performance degradation will occur when using two headphones simultaneously. See the electrical
specifications for details.
