ultraRendu dropouts at DSD512 and 768kHz

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.

Have you checked the Dena and HQ Player forums at Audiophile Style? They seem to have direct lines to customer support over there (at least I’ve seen for HQ, Lumen, and Roon).

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. 

FWIW, I have both uR and oR and have no issues upsampling to either 768KHz or DSD512 in HQP Desktop (of course, not all modulators / filters as this is computationally intensive).
