Wait a few minutes and plug in the USB DDC, and shows up a 3: SMSL USB Audio. The 0: HDMI is still the default, and have to change it in the Audio config. If you just try to play, a warning pops up saying no device detected on HDMI, and will not play or see the USB Audio at that time and switch. I assume that if the HDMI was connected to a display, it would just go on its merry way.
It didn't work that way in 8.x.x, and thanks for the explaination why.
A possible work-around, H/W solution for the OP, is using a DDC and connecting to the DAC via SPDIF (coax or optical). The SMSL PO100, $40, only draws 300mA from the USB bus. Just a suggestion.
What do you have set for "Device ready wait"?
