HDMI audio

HDMI: HDMI Audio has stopped working on my Monitor.

OPTICAL AUDIO: Don't have any Optical Audio speaker systems.

Have you checked the audio output settings on the console?

Go to settings,

select Display & Sound

select Audio Output

and there you will see a choice of either HDMI audio or optical audio.

Check to make sure HDMI audio is selected

As if it`s set to optical you will not get an audio output through the HDMI cable.

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.

The specs of the system are:

RCA RT2911 1,000W HDMI Home Theater System:•1,000W power

•145W x 4 and 210W x 2

•Full HDMI switching allows users to play HDMI audio from selected HDMI input, while also passing through the HDMI signal to TV

•3 HDMI inputs, 1 HDMI output

•Digital optical and coaxial audio inputs

•3 AUX audio inputs

•Line-in for connection to iPod and other portable audio products

•6.5mm headphone output

Xbox One has 2 outputs - one HDMI and one Optical Audio (s/pdif). HDMI carries both audio and video. But if you want to send your audio to a receiver that does not have HDMI inputs, then you can use the optical output from Xbox One. PS4 is exactly the
same.

And William is right - if you try converting HDMI to DVI, you will lose the audio on both Xbox and PS4 (unless you are using the separate optical output for audio).
