How do I connect to my A/V receiver for audio
I was comparing Apple TVs at http://www.apple.com/tv/compare/ to see which one I might buy. I noticed that the $149 model does not have any audio out so I was wondering how I get audio to my A/V receiver. The Apple TV would be connected to my TV via an HDMI cable, but then I'd have to run an audio cable to the receiver so I could use my A/V system. Has anyone done this? How does the audio sound compared to using an audio output from the Apple TV directly to the receiver?
