I have just splashed out on 2 x 2nd generation Musos and a NDX5 X2 as I have been using sonore bridge with gen 1 musos multirooming from a NDS. It was not stable set up.
I can now multi room from the Naim app but not when using Roon. I am scratching my head as the overview in the Naim app clearly indicates the multi Roon is working, however when I go to the NDX5 X2, which I use as the source there is no multi room control as there should be.
So I hope the collective wisdom will provide the answer before I start throwing my toys around!
