Recieve audio from other android device


complicated question. I use a Android TV device primarly for video and music. I also have a Raspberry PI with Hifiberry DAC and Volumio.

I then have a analog reciever connected to my Volumio setup, I want to be able to stream all audio from Android TV over network to Volumio or perhaps a Openelec install if not possible with Volumio. Any ideas on how to do this?

I can not connect my reciver to the android TV since it only has digital SPDIF output
