With cable television beginning to broadcast channels in high definition, you now have more options than ever before to get the best possible picture and sound quality for your home theater system. One of the best ways to enjoy the sound from your cable programs is to hook the audio up to a surround sound stereo. There are several ways to run the sound from your cable box through your surround sound, depending on the TV and the connections you want to use.

HDMI Connections

Set up the television, cable box and stereo in locations that are close together. Usually a home theater system has all components in one easy-to-access cabinet.

Plug an HDMI cable into the HDMI output on the cable box. Plug the other end into an HDMI input on your HDTV.

Inspect your television auxiliary sound output and your surround sound stereo auxiliary input to determine if they both have RCA ports or HDMI ports. Connect the correct cable to the television output and the surround sound input.


Place the television, stereo and cable box in the same configuration as in Section 1.

Plug component cables into your video output on the cable box. Plug the other end of the cables into a component video input on your television.

Plug RCA cables into the audio output ports of the cable box. Plug the other end of the RCA cables into the auxiliary inputs of the stereo. When you turn the television on, you will have to turn on the stereo to listen to the sound.
