I want to play my music on my computer in my home office and have the sound distributed throughout the house. Whats the best way to do this? I was wondering if I needed to add a second sound card and then run the audio to some amp in the attic and from there run to speakers but the more I think about it the more I realize I don't know what I'm doing. I need something like the Video Professor for home audio. :)

Thanks for any help in advance
