I am running Roon on a NUC with a large DSD database in DoP format on a NAS. System is a Network Bridge into a Scarlatti DAC via dual AES with no clocking. When I start a DoP album I get a distinct spitting sound through the speakers as the DAC first locks to the signal - short in duration but offputting nevertheless. Apart from the spitting sound, all tracks play fine and Scarlatti display is as one expect.
The same files play fine through Vivaldi upsampler and Rossini direct through ethernet inputs. Network Bridge is set up correctly for dual AES use, as is Scarlatti, and all are running latest firmware. The DSD albums in DoP format are not new and have been played on various dCS systems without any issues for many years. Changing the re-sync delay in Roon has only minimal effect.
Any help much appreciated.
