Question

no 5.1 audio with apple tv

I can't seem to figure this out. I have an apple tv hooked up to my home theater receiver and can't seem to get 5.1 audio from videos encoded with aac audio. i've tried multiple setting changes on the apple tv with no luck. I have a pretty old receiver so I'm thinking that the receiver does not simply support aac but when I tried a newer pioneer receiver that supposedly supports aac through HDMI, still no 5.1 audio. currently i have the audio out through optical cables and yes the settings are correct on the receiver to receive from the optical connection as I do get 2.0 sound.

Answer
You have coax audio connection?

If you do, try using that instead of optical. My understanding of optical is 2 channels only for lpcm. However, you could get surround with bitstream, which should pass through optical but the quality may not be as good as lpcm. but maybe give that a try also.

no coax

Apple TV does not have a coax connection. only optical or hdmi.

What about the TV?

It has optical audio, does it also have coax audio output?

Your hunch is correct about the receiver not supporting AAC
