Hi, I see you didn't get any replies. I don't think I have the exact same issue but I have something similar.
I used to use an ACER RL3700 nettop with W7 Home Premium to drive my Wyred 4 Sound DAC2. Audio output was WASAPI and all worked well. Using JR19.
I've now move to an Intel NUC i3 D34010WYKH running W7 Professional. I've loaded the W4S drivers but I'm only able to output Kernel Streaming. I've just loaded M2TECH HiFace drivers and again I only have Kernel Streaming. Trying WASAP gives an error message (Playback could not be started...).
Now, KS sounds fine to me but I'm interested as to why I can't use WASAPI.
Furthermore, when I go to Control Panel, Sound, the only device I see is "Remote Audio". This is even when selecting that disabled devices should be shown. Both the W4S and HiFACE are shown in device manager, sound video and game controllers.
I've asked W4S if they can help but they're scratching their heads. I wonder if anyone else on the forum who is more familiar than I am with the Intel NUC devices has seen this before and what the cause might be.
Cheers,
Jon
