Audio/Video Receivers

My set up will be:

Cable Box HDMI out to Xbox One HDMI IN, Xbox One HDMI out to Receiver HDMI In, Receiver HDMI out to TV HDMI in, Receiver Audio out to Speakers

So the Cable audio/video goes to the Xbox One, Xbox One send that and/or it's audio/video to the Receiver, Receiver sends video to TV and audio to Speakers

It seems like that's what you're describing, so I'm not sure why you think audio is being left out anywhere.

Woe, quick! Receiving video and audio now...cool..happy holidays

Basic setup with an audio/video receiver

With an audio/video (A/V) receiver, the best and most direct option is to connect the devices sequentially:

1.Connect your set-top box HDMI output to the Xbox One HDMI input.

2.Connect the Xbox One HDMI output to your A/V HDMI input.

3.Connect your A/V HDMI output to the HDMI input on your television.

Notes

•This option requires that all devices support audio over HDMI.

•Surround sound from your set-top box will not be passed through the Xbox One.

•When you perform this kind of basic setup with an A/V receiver, you’re passing both audio and video through another device. Depending on your equipment, there is a small risk of audio or video lag.

It should work. You can change what each source receives. Just set your receiver so that when you select xbox one (whatever inlut you choose) it actually reads just the optical audio. Then when you snap to ps3, youll have to also select the ps3 on the receiver.
the xbox will still broadcast video to projector and the receiver will do audio. What I want to test is if the hdmi in is 2 way. If it is you just select the OUTPUT on the receiver (usually called tv) and that would do audio out and in and video just goes
to projectory. Then you select tv for xbox one
