How do I stream my computer audio to Skype?

For the love of f***,how do I stream my computers audio to skype? On the Mac, it's easy as hell (just install soundflower, and use that as the audio device), but nothing is working on PC. I tried like 4 different methods (stereo mix, Vistula audio cable, jack router) and it either has horrendous lag (I want to stream a DAW while I play piano with midi, so I need low latency), or it doesn't show up in skype. For example, jack router doesmt show up in skype, VAC has garbage latency. And "stereo mix" doesn't pick up my computer/system audio (ie when I select stereo mix in skype, the audio bar never moves). It's 2014 for f***s sake.
