This project is in the back burner… It never worked well… Alexa seems to fail badly when music is playing, and the fact that Roon sounds like Room makes it even worse.
We could release it, but it’d be a very poor product. Additionally, no one on our team would want to live with it, so it would slowly wither and just be a sore spot for Roon members who would expect a high quality product.
The idea is great, but the implementation isn’t there… 
We will revisit with future software updates
