I've done everything I could think of to get Poly to work like this. I only get to change options when I connect Mojo directly to the computer. When Mojopoly is connected Roon says it's Roon ready but uncertified. When I go to settings I can't make any changes to DSD processing (or even get the option) since Roon doesn't know the device has DSD-capabilities it appears. I can push settings to 32/384 and that's it, I've tried nearly every option in with or without the DSP-menu to get it to process DSD directly but no luck.
DSP is completely disabled but it is activated every time some DFF or DSF file plays.
I figured it out. DSD playback in Roon was activated when I looked at it before in GoFigure. I just went back in Gofigure and quickly deactivated and activated the tab again. Now it works.... Go figure.
