All topics I found with a search for Mconnect were closed, hence the new one.
Just wanted to report that when using Mconnect now it´s all working just fine. When I tried it this spring I got buffer overruns on the NDS. Now hires from Qobuz are working as they should.
I really hope this solution holds since it´s a pain to use bubble upnp and Roon, not to mention the cost for Roon.
