No idea what is going on if I’m honest.
I never noticed this to be an issue until recently when I started getting big jumps in volume even when levelling applied in Roon. When I checked the signal path, levelling was zero and that’s when I figured it was something wrong.
Old releases don’t have this problem.
Maybe it takes a while for Qobuz to provide this info to Roon or scan their catalogue but I have releases from one week ago and still no volume levelling.
