SOtM to Schiit Eitr

Hi Guys

I have a SOtM ultra neo and I connect it directly to a Mytek manhattan DAC using USB and I am able to stream Roon to SOtM. I also have another DAC that only takes spdif inputs. So I bought a Schiit Eitr (Digital to Digital converter) and connected the output of SOtM to the Schiit and a SPDIF cable from the Schiit to the DAC. Now my Roon is not recognizing my SOtM. Any thoughts?
