I just ripped a BD-A (Mozart Symphonies, Karl Böhm, DG) and one track from about 180 is recognised falsely as 48kHz instead of 192kHz, and plays back at 1/4 speed. All other tracks are correct.
I’ve done the extraction twice, once over the network and once to a local USB drive, with the same effect.
Happy to provide the track (and another correctly played one as control if you want).
