thank you; I found the settings here: iFI Zen Stream to Peachtree Nova is DSD Native Possible? - #18 by Michael_Harris
I don’t want to upsample everything to DSD, just native DSD. I found the updated firmware, and the device Roon now recognizes it. there are a few oddities however:
USB output only works in AIO mode; if I switch to Roon only, Roon shows it as playing, but there is no sound. SPDIF works as expected.
Also, I can’t get sound with DSD, although my dad (Quad VA-One+) supports it natively. again, Roon, and the iFi app show it playing, and being sent to the doc, but I get no sound.
lastly, the iFi app won’t let me set DSD Direct. I can change it, but when I save it it reverts back to DoP.
