Be careful. Be sure you can return this.
You did write "streaming" so here's the trouble area. To stream the content is packaged up and sent over some network and in doing so introduces a delay. An extreme example where delays are outlandish is at http://www.wired.com/wiredscience/2008/12/speed-of-sound-in-football-stadium/
So be sure to keep your signals wired as packetising and such will cause trouble and get you upset.
If you can't hear the other room then that's not a concern here.
