Sorry Miguel , somehow I read your original post as “un-unfolded”. I put it down to an absence of alcohol during Sober October 
.
Yes I think that is correct. Actually your question seems to resemble one from last week:
Bartók and MQA — which USB input?
So, two queries along the same lines suggests that something is going on. There is the question of the source of MQA files being processed by Roon but I wonder if they have changed something perhaps unwittingly? We do at least know that there have been no recent software updates to the dCS lines so that hopefully eliminates the dCS end of things.
