The “Analog Input Volume” tab provides high-level control of all volume settings in the ADC of the CS42L55.
Status text detailing the CODEC’s specific configuration is shown inside the control group of the affected
control. This text will change depending on the setting of the associated control. A description of each con-
trol group is outlined below (a description of each register is included in the CS42L55 data sheet):
Digital Volume Control - Digital volume controls and adjustments (ADC output).
ALC Configuration - Configuration settings for the Automatic Level Control (ALC).
Analog Volume Control - Analog volume controls and adjustments (PGA and MIC amps).
Noise Gate Configuration - All configuration settings for the noise gate.
Update - Reads all registers in the CS42L55 and reflects the current values in the GUI.
Reset - Resets the CS42L55.
