WTF? I don't mean to be rude but why would you use HDMI on a pc to output digital to a dac (unless that is all it has)? Why not forget the $28 most likely piece of crap "converter" (or whatever you wish to call it) and use a decent usb dac? There is no rule saying you have to add extra shit in the middle of the audio chain to get good sound. One just needs to not buy a shitty usb dac, that's all.
