It won’t come under Roon tested unless it’s a networked device which this isnt. If it’s Roon tested as a DAC you just get it recognised properly and with artwork to identify it, rather than as an unidentified device like this.
Not for dacs they don’t show as Roon tested. My DFB nor DFC never has. They are attached to a core or bridge which is what shows up they don’t appear under Roon tested even though they are. They are only identifed, where non Roon Tested dacs show as unrecognised.
My DFB which is Roon Tested
Yes, only network connected devices show up in those categories. Roon Tested will show streamers, preamps and amps that connect to Roon not by RAAT but via Airplay, Sonos (S1 devices), Chromecast, KEF, Linn etc that have been tested by Roon, other ones that have not been officially tested but work show as Other Network Devices. Not all Airplay or Chromecast or the latest Sonos stuff show as Roon tested as they havent tested them but they will work.
