DAC

The bits has to be translated into an electrical signal to become audible.

This is done by a Digital to Analogue Converter.

The receivers extracts the data (the signal) and the clock from incoming signal.
In general this is S/PDIF over coax or Toslink. Modern DACs offers USB input to.
A digital filter might be used to do SRC (sample rate conversion)
Some DACs do reclocking, it makes them immune to jitter in the input.
The DAC chip converts the digits to a current
The current is converted into a voltage (IV converter)
This signal is filtered to get rid of the switching noise.
The amplifier is needed to bring the signal up to line level (just like a phono stage).
