Today I briefly test my pi zero w with friend's Fiio Q1 dac amp and for a few minutes i hear NO glitch. alas I can only test for a few minutes because mpd seems not to recognize the dac after a while and reboot did not help either. This motivates me to do a usb cable Y hack (one usb to pi and one to power source. I use this before to help power the dac while I'm using phone otg) and power the dac independently.
still glitch. back to square one
