Is there a way to get the Apple TV2 to push simulated 5.1 to my home theater system via a digital audio cable for music streamed through iTunes? When ever I stream music to my Apple TV it only sends 2.1 audio to my receiver. Any help would be appreciated as I would like to get the most out of my surround sound system! The whole reason I bought it was so I could stream music to my surround sound system.
