Convert DD+ to DD 5.1

[Solhokuten]

Is there a device I can use to convert DD+ to DD 5.1. I'm trying to get 5.1 surround out of the Netflix app on my Nvidia Shield TV with Logitech Z-5500. I know this is a long shot, but figured I'd ask anyway.

I think you need to get an HDMI receiver / preamp (a lot of mid-hi grade receivers have analog pre-outs, that might work if you have discrete analog inputs on the logitech)

But as far as a simple solution - it looks like a no:
