Thank you for the post, RoyalScam. I haven't contacted Qobuz, but your suggestion prompted me to go back after un-favouriting one of the selections. It still gives the same message when I try to play it in CD-quality. Interestingly, I noticed the album now has a Hi-RES identifier below the album artwork, which wasn't there before (or maybe I just didn't notice it before). I tried switching my preference to the Hi-RES this time and voilà ! it plays in Hi-RES ! In the past, I have been able to play a Hi-RES album in any format. What is weird is that this particular album, the last one I had this trouble with, will play in Mp3 or in Hi-RES but not on the CD-quality setting. I'm just happy that at least I'm not limited to Mp3. whew! thanks again for the suggestions!
