alt Hacker NewsIn the meantime, what would you recommend (if there's anything off-the-shelf that would work in a plug-and-play manner?)
I had a project in mind that was waiting for something like this! :)

It is not 100% plug and play as you can choose your own software.
For USB input and SPDIF output, all that you need is a TOSLINK TX module(s) or a couple of capacitors and a resistor if you want coaxial SPDIF. For I2S output, the PCM5102A modules that you find on Amazon work very well, with very reasonable performance (SNR >100dB, THD+N ~95dB).
For 2.1 configurations in a pinch, the firmware includes a software DAC that's more than adequate to drive a subwoofer, so only one external DAC is needed.
