Soundflower in Yosemite (and probably Mavericks and El Capitan)

Hey, Mac audio enthusiasts/podcasters/professionals! If you're a fan of Soundflower, the useful audio input/output kernel extension and its extra appendage utility, Soundflowerbed, you may have been frustrated by how everything got all messed up when you upgraded to Yosemite (or Mavericks, or El Capitan; this post is Yosemite-centric but probably applies to those other OS versions, too).

This should give you the functionality you need. It worked for me.
