 > I don't see why it would be an MDAC, as others are saying, because 
there's no DAC. The signal stays in the analog domain.

It does but the level control is digital. The MDAC will use the audio 
signal as the Vref for the DAC resistor ladder.

A DPOT can be considered as just an MDAC without the output buffering 
but adding the capability for a two terminal input rather than a ground 
referenced voltage input.
