Default AWDSPx8, high-end DSP DAC(s)

New project in the making

In short: Audio Widget as USB-I2S -> ADAU1452 DSP as XO->4x PCM1794A DACs with passive I/V, meant for driving directly amps with 3way speakers + SUB, or 4way. Sort of a digital preamp with XO.

Scratch that, it will be ADAU1452 instead of ADAU1701. Not enough resources in ADAU1701 for 4 way XO with volume control, and I am not using it's DAC's anyway.

Almost there! SPDIF in and out added. Or maybe I should put just two SPDIF inputs?

Added display and encoder to Arduino, as well as ability to control digital filters on PCM1794A.
