You have no interest in streaming, but you want to use Roon? 
Roon RAAT is also streaming - just like UPnP and Devialet Air. It's just different protocol.
If Devialet Air is also not working well from Roon - you have some major issue either with your network or with your Devialet Expert. I don't have any problems with Roon - both with RAAT and Air. They both work perfect, but I use UPnP because it sounds better than Roon.
