Hi guys, i'm trying to wrap my head around how apple tv, apple airports, and airplay all work, kind of a lot to take in, I feel like i'm way behind on times here! After my last PC died again I decided to just go all out apple. So i have an iPhone, iPad, iPod, and an iMac now. Might as well attempt to integrate everything! Anyway, my goal is to be able to use my iPad or iPhone to control the music on my patio. Right now in my garage I have a samsung flat screen with a samsung surround sound that has a dish network box on it. Currently I just turn on the XM channel I want and the surround sound plays it through my patio and or garage speakers. It's a pain because if I want to change the volume I have to get up and walk to the garage to turn it up or down. And i'm locked into that xm channel unless I walk to the garage and turn the channel. I now have a wifi extender and have awesome wifi signal all through the garage and all over my patio. My buddy gave me an apple airport express that he no longer uses. I was curious if I could use that to accomplish something here. Do I need an apple tv box to do this? I have no idea what my options are, nor do I have any clue of how to go about making this happen. I just know that there has got to be a better set up then what i'm doing now. Can someone please educate me?
