I use Windows 10 and Mac OS X with optical via my onboard sound and USB via a USB 2.0 port. 

In both OSes, when I use the device over USB it seems to shut off or go to sleep every time there is no sound. This causes a half second delay in hearing new sound, which basically means I can't use it as my external sound card because no notification sounds will ever be heard. Is there some way to get it not to go to sleep? 

Also, I had significant popping when I tried to play a 16-bit / 44.1 file while in DAD 32-bit / 384 mode. Also YouTube videos basically had no sound when the OS was set in this mode in Windows 10. In Mac OS X it seems to work sometimes. I set the bit rate in the Audio MIDI Setup utility to the 32-bit 384 and it either works, or I get significant popping. I'm guessing the USB can't timing sync with the computer? 

Anyway, I mostly use Mac OS X (Hackintosh setup) but on both OSes I'd love to be able to shut off the onboard audio completely and just use the NFB-11 as my USB sound device in both OSes for all system sound.

On the plus side, I don't mind the 24-bit/96khz optical, which works flawlessly and the sound is incredible to be sure. 

Here's my part list:

Motherboard is an Asus Z97 Sabertooth Mark 1 with the latest BIOS. 
Nice post, I have to say the sound from usb is inferior than optical even though usb has much better threshold on paper.
