First of all, I love my new Onkyo Tx-NR807 it has made my speakers sound better than I have ever heard them. I am running into a problem I hope I can overcome with the help of a few more brains after it.
I am searching for a way to play a different audio source than what is playing on the TV. Let me explain. I like to watch sports and play video games while not listening to the audio from those sources. I have an appleTV which I have installed XBMC on and use an iPhone app to control it remotely without needing to see the screen to select music. I would like to know of a way to play a video game while at the same time listening to the audio from my appleTV.
