Connect Xbox One to Your Home Theater or Sound System

Would suggest you read thru that link as it has setup options depending on your system. I have a home theater with surround sound but the HDMI runs thru it as well it is not direct to TV.

If you have an Xbox 360 Slim* connected to your home theater system (HTS) via an HDMI cable, you will be able to hear the game audio through both your DSS2-upgraded headset and your HTS using
the standard setup procedure. To do this:

1. Connect the included digital optical cable to the Digital In jack on the DSS2, and to the S/PDIF jack on your Xbox 360 Slim (or the Digital Output jack on a PS3).
2. Keep the HDMI cable connected to your game console and HTS as normal.
3. If you have a WIRED headset, connect the headset's green 3.5 mm plug to the headphones jack on the front of the DSS2. Then, connect the headset's USB plug (if it has one) to the USB port on the front of the DSS2.
4. Done! You should now be able to hear the audio from your game console both in your headset and through your HTS. You can adjust the headset volume and the HTS volume independently of one another.

Hello trickybuz93, thanks for posting in the forums to get some help. Information about connecting your xbox to a home theater can be found here:

Bottom line is you need a separate optical cable to connect to a home theater system. The HDMI apparently doesn't carry the audio.

Hi there FourscoreSteam9,

Thanks for reaching out here in Xbox Forums. I understand there is an issue with sound and video issues while connecting your Xbox One to a home theater system. I recommend to try check out the following articles for more information:

• How to connect your Xbox One to your home theater system
• Troubleshoot sound on your Xbox One console

Try this out and let us know the results.

I think it would work if you remove the SCART cable between the Virgin box and the TV, and move the other SCART cable going to the home theater system from the Virgin box directly over to one of the SCART inputs on the TV.

Check the cables to see if they have any labels on the connectors. If one end is labelled "TV" and the other "DVD" or similar, it's wired to carry signals in one direction only. If you have a cable like that, use it between the Virgin box (DVD labelled end)
and the home theater system (TV labelled end), and the other cable between the TV and the home theater system. If both cables are labelled this way, you need to pick up a fully wired SCART cable to go between the TV and home theater system.

Connected that way, the DVD player will input picture straight to the TV instead of going through the Virgin box, and the sound from both the Virgin box and the Xbox 360 will be sent to the home theater system back through the SCART cable.

If this works, then leave Dolby Pro Logic II enabled for both games and TV - both will benefit from it.

Hope that this helps.
