I think also the digital bypass seems just "Digital loop". Not specifically related to the TWL4030 (I've never particularly looked at that device) but many devices have the ability to do paths where the audio flows from an analogue input to an analogue output via an ADC and a DAC, possibly with some sort of signal processing going on in the digital domain.
