Thank you for the reply, Paul. When I initially connected the device to the network it simply was not recognized in Roon. About 30 minutes ago worked out that the R26 had to be in LAN mode (which it had not been) to appear in the Room audio settings. I have enabled it and after some more trial and error (set Roon settings to convert from DSD to PCM) was able to get some sound from my system. There is very little information out there to use this Gustard as a streamer. Anyway, for the time being, I am happy now that it is actually working as a streamer. Thanks again for your reply.
