My plan is to have my Comcast Motorola DVR plugged into my HDMI in port on the One. Currently my Comcast DVR goes into my receiver for the video and audio. If I just put my HDMI that is in my receiver into the Xbox One, will the audio function the same? I Have looked all over to verify that the One will pass the audio and video to the receiver. My 360 has an optical audio out since the 360's audio is nothing special. Will plugging my Xbox One into the receiver via HDMI play both the audio for the games and the TV? The fear I have is that there will be an audio lag when watching TV like the lips being slightly out of sync.
