That was it Arlen. I had streaming quality set to High but not Max. As soon as I switched to Max and tried the same album it successfully started playing the high sample rate versions. Thx!
The odd thing is that I often played high sample rate files via Tidal and it had no issue playing at the correct rates. For some reason, a few of the FLAC albums got dumbed-down to 44.1/16.
So did the Tidal setting in Roon get set to Max automatically? I certainly never changed that after my initial setup a few years ago (where I’d selected the highest option available at that time).
I can’t remember (and probably this should have been mentioned in the release notes) but there were definitely many instances of the same kind here on the forum.
