ultraRendu dropouts at DSD512 and 768kHz

I'm working on solving a problem, and not making the headway I'd like. 

I recently received an ultraRendu to use with Roon and HQPlayer as a network audio adaptor (NAA). I am having trouble with the music stuttering or dropping out, primarily at DSD512 and 768 kHz, which are the maximum specs for the ultraRendu. 

My setup currently is Apple M2 Ultra (Roon or HQPlayer) ---> (Gigabit Ethernet Switch (4 different types tried (both managed and unmanaged) ---> ultraRendu ----> Denafrips (Hermes DDC or Terminator 2). 

 

Has anyone dealt with this before, have any helpful insights, or can point to a forum where this problem is discuss in detail?

 

Thanks

Discovered the issue. 
 

Sonore is having trouble with firmware version 2.9 working on all Denafrips models. I did an OTA update of 2.9 to make sure it was properly installed, and now the ultraRendu is completely unable to interface with the Denafrips. No music whatsoever. 
 

Customer support is trying to work with me to flash to 2.8, which I think means mailing out a new SD card. It’s going to take some time, and even then, I am not sure it’s going to work at the highest output settings (DSD 512 and 768 kHz).

 

I will report back when I know more.

Thanks for the suggestion. I haven’t been there specifically to check the forums, but it sounds like it might be worth a few minutes to check out. 
 

To be fair, customer service at Sonore and SmallGreenComputer have both been responsive to emails over the weekend, which is somewhat uncommon. I’m not convinced they have a solution right now, but to their credit, they do seem to care.
