RELEASE Generic Media Renderer (DLNA Speakers). Cheap Sonos Alternative (Update V2)

I was able to get my Pioneer to be picked up.

Here is the issue. On my Pioneer when I tested it via EchoSistant (http://thingsthataresmart.wiki/index.php?title=EchoSistant) it changes to the ui for the speaker (different) input, and it didnt go back to the input it was on originally. I thought the sound would just come out of the input it was on. I guess not. If the speaker has to switch, what can I use to switch it back? CoRe maybe?
