I am using a sony blu ray/dvd palyer model bdp - 5380 with that logo that I can play those discs as you said some were in 5.1 so maybe when the mass produced it they put the label on a 5.1 in a 4.0 case. i remeber some of the old A&M record labels on the
orche label like the old TJB they used a mono cover and put the stereo disc in the cover and with a sticker that said in an oval label stereo. so who knows. strange things happening.like the blood sweat & tears one I got with spinning wheel it did paly in 4.0
I wish adio fideilty would release carly simon no secrets with your so vain. and nilsson smilsson with jump into the fire that drum solo as I remeber it from my CD 4 disc was great coming from all 4 speakers would be nice to hear those 2 again

You're still off the mark somewhere. I used a Sony Blu-Ray player with SACD compatibility for years, so do one more thing.
Go into settings and then music settings. First, make sure that under "Super Audio CD Playback Layer" it's set to "Super Audio CD", then under "Super Audio CD Playback Channel" make sure it's set to "DSD Multi".
Once you check that, then tell me what you hear after that.
