Apple TV and rMbp

[ducatiti]

Plan to hook these up to my 7.1 system. If I connect an Apple TV to my receiver, will this output audio as well or do I need a separate optical cable? Or is there a particular Hdmi cable needed that can handle audio as well?

Thank you in advance.

HDMI does both video and audio.

edit.. didn't see the 7.1. dunno all the detail about apple, just hooked mine up via hdmi.

Not sure what the optical port is capable of.

Optical repeats the HDMI audio signal.
Just a side note: no 7.1 sound from AppleTV (at least unjailbroken) 'coz it only can pass through Dolby Digital 5.1
