Pin Configuration Default Register Settings
The configuration default registers are 32-bit registers required for each pin widget. These registers are normally used
by the CODEC driver to determine the configuration of jacks and devices attached to the CODEC. When the CODEC is
powered on, these registers are loaded with the default values provided by IDT for typical system usage, and are
loaded in a way that is compatible with the Microsoft Universal Audio Architecture (UAA) driver. The values can be
overridden by IDT customers according to their system configuration. Table shows the Pin Widget Configuration
Default settings.
The settings reflect the Consumer Desktop use model with:
Independent Front Headphone and Microphone for real time communication
7.1 audio output at the rear
Rear Microphone and Line Input jacks
Optical SPDIF input and output jacks at the rear
HDMI
Digital Microphones are connected as a 4-mic array (Volume Knob Widget is visible, but inactive)
Analog CD input is connected to an internal ATAPI connector.
