Have you chosen the correct output of the PC in audio settings. You will need the driver installed for the highest DSD output and choose the ASIO output option in audio settings. If using WASAPi ensue your in exclusive mode.
Exckusive mode is ON, but it does not give the Native options.Dac has XMOS XU-316. The driver is from the SMSL site. I don’t know if i need to instal another driver in addition to the factory one, or it has to do with some serings in Win.
I would have thought the driver would be for ASIO to get over WASAPI imitations. If so this should show up in settings/audio. If you have set exclusive mode it’s using WASAPI not ASIO. But it should show up DSD options anyway I would have thought. Can you show a screen grab of Roons Settings Audio so can see what it’s showing as zones available connected to the PC.
