I have an Esoteric K-03 SACD/CD player and Windows 10 on my laptop. The Esoteric has 3 settings for the USB input: Nor (normal) and two HS (hi speed). I installed its driver on my laptop that allows for the 2 hi-speed modes (they can handle a higher sampling rate than Nor mode, which doesn't require a special driver), but it disappears from the JR audio device list whenever I switch modes, and then my computer defaults to its internal audio driver. Also, I get no audio with either hi-speed mode. I will greatly appreciate any help anyone can offer.
