USB as output on 120?

[thumb5]

Didn't work :-(

Doesn't surprise me in the least, but: nothing ventured, nothing gained.

Maybe my DAC (and old Streamer+) could not handle the input. Maybe the new cable was not the answer.

As I said, the problem is that both the Devialet and the DAC are USB peripherals.  USB requires one "end" of the link to act as a host and one as a peripheral -- and they have to have both different hardware and different software to achieve this.  It's far more complicated than just connecting a cable with the right type of connectors; indeed the whole point of the different types of USB connectors is to make it difficult to connect together two hosts or two peripherals, since that's a combination that won't work in general.  (This is a bit of a simplification, forgetting about OTG.)

What I know is my computer saw a signal but would not translate that to audio out without software.

When you say "saw a signal" -- I think you said earlier that you saw "input meters moving with the music" -- that suggests the computer must have the appropriate drivers to act as a USB host and communicate with the Devialet audio peripheral device.  Translating that to audio output should then just be a matter of using suitable media player software and choosing the Devialet as an audio input device.  There are some instructions on Microsoft's web site that describe one way to do this.
