Problems with Core Infinity

[Confused]

Hi Devialet owners

Maybe someone have learned how to deal with the following issue and can share the solution.
I have a new pro 220 with CI. It is connected to the network NAS Qnap 451+, router, Mac mini. . On Mac I have all three players for testing roon Audirvana and Amarra. 

The problem is that upnp mode is not “stable”I get an ikon for network appearing and disappearing on the screen of Devialet. When I look for audio output to chose unpn Devialet, Amarra and roon do not see Devialet. Audirvana can see it, but again it appears and disappears, so even if I’m in time to chose it from the drop box, it changes to Inbuild audio in a second . I run the latest beta on Devialet. Roon through air is ok, usb play is also ok.  What I want to achieve is Audirvana through upnp as I do not want to listen to USB cable (effects the. Sq)

Anyone out there can help a frustrated audiophile?
Kind regards
Alex

Have you tried using Devialet AIR?  (Or Roon integrated AIR). There is a good chance it will work well with your Mac Mini, there is a good chance it will sound better than UPnP too.

Edit: see also Axel’s response in the listening impressions thread, in addition, Roon can do DSD to PCM conversions, which might work with AIR.
