Comcast HDMI-in w/ HDMI-out to projector, optical audio to AV receiver: no sound

Greetings--

I have an older projector that does not handshake properly with my newer AV receiver (5.1 surround sound) via HDCP. So I've used optical audio out to successfully get sound. Before introducing the Xbox, then, I had my Comcast box HDMI-out directly wired
to my projector, and the Comcast box digital audio-out connect to the AV receiver. This works fine.

I introduced the Xbox. So now I have:

Comcast box HDMI-out to Xbox HDMI-In.

Xbox HDMI-out to project

Xbox digital-audio out to the AV receiver.

This works fine when using the Xbox itself. However, for "Live TV:" I receive a picture fine, but cannot get audio working.

I can manually switch the optical audio to output directly from the Comcast box to the AV receiver, and of course this works (but I'd rather not of course).

I've mucked with all of the Audio settings (for the console itself as well as those under live TV) and nothing appears to generate sound on live TV.

Is the Xbox capable of converting the HDMI-in signal from the cable box and sending it out over digital audio (and of course still send the image via HDMI out)?

Any help greatly appreciated. I searched but did not see a post with a setup the same as mine.

No Audio from Comcast Cable Box through HDMI.

When I connect my cable box (Comcast) to my XBox One, I get no sound through the HDMI cable. My XBox Audio is fine.

Display and Sound: TV Connection HDMI.

Devices TV (Visio Model Selected). Cable or Satellite Box (Comcast Selected).

Audio Receiver (Not Set)

HDMI Audio Stereo Uncompressed

Optical Audio Off

 

Xbox One and Projector?

In regards to the video/audio split

Ideal scenario:

You have a newer receiver that accepts multiple HDMI inputs. Using HDMI this will allow the sound to run through the receiver first thus outputting sound there. Sure you'll have to mute the projector sound.

My setup:

An older receiver with optical inputs, but no HDMI. I bypass the receiver for all video using a small HDMI auto switching box ($10 on Amazon). Use the receiver for sound only, usually the optical. Since the HDMI box auto switches, there are no more steps
to changing the source then if I had a newer receiver. The sound does travel through the HDMI still, but I just mute the projector.

This works great until I want to hook something up that has ONLY HDMI, such as the latest design for the Xbox 360. I would need some sort of contraption that splits the two, which I think are out there.

If your stereo/receiver doesn't accept optical...then you could try this
