On Sonicorbiter 2.6 and newer versions the sonicTransporter series will have Signalyst HQPlayer 4 Embedded.
I have been testing it this morning on my system as follows and its working great:
1. Roon with HQ player added as a network audio device
2. Sonicorbiter 2.6 running on sonicTransporter i5
3. ultraRendu with NAA as output mode
Here is a screen shot of the HQPlayer 4 Embedded configuration page on the sonicTransporter i5 set to up sample all PCM to 96k and pass DSD without conversion.

FYI my Signalyst HQ Player 101 guide will assist you with the setup parameter:
