Need some help connecting a Sony Home System Theatre surround sound up to my Dynex TV!?

I bought the hdmi cable,stereo audio cable, and the sony digital audio optical cable (which cannot plug into my tv) how do I do this? Also I have an xbox plugged into my tv if that is a problem? Thanks!

If your Sony Home Theater system has HDMI inputs you want to do this.
HDMI cables from you you DVD, Blu-ray, Xbox into your Sony System.
Then attach an HDMI cable from the output of you Sony system to your Dynex TV.

Sound will be transmitted via HDMI to your Theater system and the video will go from your device to the sony system and then to yoru TV.
This is a typical setup.

If your Sony system does not have HDMI then you will want to do the following.
HDMI to your TV and Optical Audio cable to the Sony system.

This will let you hear audio form you Sony system and still have Video to your TV.

If doing the second option you will have to set your devices to output video through the HDMI and output audio through the Optical Audio cable. Otherwise they will default to outputting both audio and video through the HDMI and ignoring the other connections.
