The Digital-To-Analog-Converter (DAC for short) is a hardware-part, you can 
not replace it by something software (1). And as the WRT doesn't have DACs on 
the outputs (at least not with the resolution you want), you can never use it 
to output analog audio signals.

That would be a box which accepts digital audio over ethernet and outputs 
analog audio. Something like a small computer running netjack...

1: Well, maybe you can try to create a Pulse-Width-Modulated analog-signal, 
but that probably not the audio-quality you want and will take you probably 
ages to program/develop...
