Keep in mind that in Windows, this is not supported. You can have a few devices and use DLNA and more but let's get this out of the way. -> NOT A NATIVE FEATURE.
Are you trying to duplicate a SONOS system?
I am trying to find a way to play multiple audio tracks from one computer and split them between different outputs/channels. The goal is to have different audio in multiple rooms but all the audio is controlled from one system or or computer
Very easy in windows too! Just get a free version of VLC portable player here: http://portableapps.com/apps/music_video/vlc_portable
Then you will be able to open up as many of the same portable player as you want and play different songs in each. Give it a try, it really works! Cheers
