SO, what gives? Any other Note 8 owners have the same problem?
You should request Samsung to fix the issue.
In the mean time, you could use USB Audio Player PRO (UAPP) which includes its own USB audio soft driver.
For the time being, to my ears, UAPP is the best sound quality music player.
It doesn't perform resampling like other music players which have to use the Android media player framework.
And the Android media player framework resamples any input sample rate to 48 kHz for the time being.
