I am using a AMD FX6300 on a Gigabyte 970A-UD3P mobo. I have an Asus Xonar soundcard that I use for optical outout, but this should be irrelevant to the USB problem. I am running Windows 10.
Before I left for work today, I briefly plugged my DAC19 into my work Macbook Pro to see if it would work. The USB module gets recognized as an audio output device, but when I select it and play music through it, I hear no output. When I switch back to my onboard speakers, I get sound again.
I am going to investigate further tonight with my Macbook Pro, Chrome OS laptops, and my roommate's Linux machine. Perhaps this is a USB module problem?
How did you end up resolving this problem, by the way? Kingwa pretty much washed his hands clean of this and told me it's an issue with Windows and that I have to debug it myself.
Well, when a device just stops being recognized on every PC you can't really blame the machine
