Below is my home layout. I've got most things setup the way I want. To get the line-in on my mini to play through the speakers (the TV) I am currently using LineIn. This works and does exactly what I want, but it has a window thats always open. Is there a background application or service that I can have always run that will do the same thing?

I know there is AirFoil but it does way more than I need or want. I just want a simple Line-In to speaker passthrough that runs in the background. Ideally even when a user is not logged in.

(yes lots of extra stuff in the picture, I got tired of making small specific pictures and just made one for everything)

Before I submit this as an answer, have you tried Soundflower, and/or can it solve your problem? – timothymh Jan 18 '12 at 21:24
@TimothyMueller-Harder it seems like Soundflower is an application thing, take the sound output from one application and use it as the input for another application. I don't see any options to have Soundflower passthrough line-in to speakers. – Justin808 Jan 18 '12 at 21:39
I'm sorry! I don't know what I was thinking. At this point, I'd suggest LineIn, but I see you've already said that you want a background application. :\ – timothymh Jan 18 '12 at 21:49
