Hegel USB and ROON suport

Hi. I am reaching out to many of you that have more knowledge and experience with implementing digital audio systems in an effort to determine if there is a practical solution to the problems I am experiencing. Let me explain.

I have a system consisting of a Hegel integrated amplifier with an internal DAC. I stream music via Tidal and Qobuz through a Zenith SE MkII via USB output into the USB input on my amplifier. I have recently experienced two problems with this setup.

Problem #1 the USB ports between the server and the amplifier are not compatible, probably due to proprietary implementations by both manufacturers. I seemed toot being seen in R have resolved this by using an iFi USB Purifier3.

Problem #2 I have setup the Zenith SE as a ROON Core and player in the INNUOS OS. The problem I an experiencing is that the ROON software does not properly recognize the Hegel amp and results in the amp not being seen in the ROON software, or on occasion, it is recognized and does play for a minute to two before drop out and no longer able to play. 

I have contacted Hegel, Innuos and ROON regarding this problem and although they have not provided much clarity related to this problem, it seems to me that Hegel does not support ROON implementation via Linux OS as implemented in the Innuos Zenith MKII. 

Can anyone that has experienced this problem with the Hegel and Zenith and understands this issue offer a practical solution that will resolve this problem while preserving the highest sound quality.  To be clear, I would like to continue to use ROON but I am open to alternatives as well. Thanks for your help.
