I had a problem where the DS Jr (delivered last week) did not see the Roon. I updated the bridge firmware and I was able to access it. However it is listed as Uncertified:
Feedback from Roon indicates this is a PSA firmware issue:
That CDMCM-210 string is the problem–A fully updated DSJr would identify itself as a “PS Audio DSJr DAC”, which Roon would recognize properly.
So, something has gone wrong with your firmware update on the DAC–if I recall correctly, this points towards a problem with the portion of the update that took place over USB, but PS Audio is in a better position to make the final determination
