ya know, I was about to answer yes and then decided to try it out. No!
You can monitor the digital inputs thru headphone out and the analog outputs work but the digital outs do not.
Looking at the signal path, I think I understand why and if it's important I could probably tell you what you need to do to bridge that. The normal digimod jumps the 24/96 digital out of the AK4524 codec directly to the CS8420, which resamples and feeds the digital outputs. When using digital input, that codec is not coming into play so the jumper does nothing. And without a pc, there's nothing to bridge the gap that would occur thru the USB path. it's the secondary d>a that provides the monitoring signal but does not feed the CS8420/digital outs. So it's just a matter of tapping into that digital signal and jumping it to the same spot as the digimod.
Problem is you'd need to switch that one off when using the analog inputs or you'd probably get the double signal effect that trashes the sound (the same one that occurs with a digimod if you plug some headphones in, turn the monitor on and turn up the volume). In a normal digimod this effect only occurs on the analog output, not the digital output, but this 2nd mod would bring it over to the digital out.
