When I connect my ūRendu to my Directstream DAC via USB and play a Bit Perfect track from NAS, by using the MConnect control point the DS indicate ‘Bit Perfect’ in its display. Then I hook up my Rockna Wavedream Net transport to the DS over I2s and play the same bit perfect file and but no ‘bit perfect’ annunciation appear on the DS when using Roon as Playpoint. Roon server v.1.3 and library is located on an SBC inside the transport. I have revisited all Roon settings together with Rockna without luck. The critical issue here is that the Rockna updates its firmware by playing a wav file in bit perfect mode. Rockna succeed to upgrade but I am not by using Roon.
The Volume control is set to ‘Fixed’
I am also providing some screenshots.
