Im about to buy an Apple TV and have a quick question. Right now I constantly listen to music through my receiver while playing xbox on my tv. Xbox sound plays through the tv, while music plays through the receiver. Now, if I hook an optical audio out of the back of the apple tv and into my receiver, will it play the audio from itunes match even when my TV input is on the xbox input and not the apple tv input? I hope I worded that clearly. Thanks.
