ROON Bridge doesn’t see Ayon Stratos

Hey all,

so am very happy with the ROON product, so much so that I would like it to see the Ayon Stratos dac as an exclusive end point. System is currently ROON on windows 11 through all in one Lenovo, Ethernet to Bluesound Node Icon as a transport, USB to Stratos- Auris pre amp and onto Parasound JC1s and JBL 4367. I download bridge with icon and dac all powered up but the Stratos dac did not appear in the audio list. Do I need it attached directly to a nucleus et al for it to be’seen’ ?
