Hi Sirs,
Does the volume control register of the TAS2557 locate at page 0x3C, register 0x70~0x73 (I captured data from PPC3 GUI and made the enclosed table)
The PPC3 GUI writes the following I2C commands when dragging volume control bar in the tuning page.
Do we have equation to calculate the volume control registers?
