For External Sources such as HD Cable Boxes, HD Satellite Boxes, Blu-ray players, DVD players, etc.:
To send the audio from a cable box of other source you will need to connect the audio out or digital audio out (coaxal) to your home theater.
Note: You might experience A/V Sync (Lip-sync) issues if you use the above method, in which case you will have to use audio/video lag correction features or speaker distance control in your Home Theater
For Internal TV sources which are received via the TV’s tuner such as Over the Air broadcasts, Digital Cable without a cable box:
To send the audio from the TV or cable without a box you will need to have audio outputs on the TV to connect to the Home Theater.
Audio Inputs on the HTS:
Based on your HTS model number, your HTS will have either:
Coaxial Digital Audio (S/PDIF) [Orange or Black RCA Jack]
Coaxial Digital Audio (S/PDIF) [Orange or Black RCA Jack] and L/R (Stereo) Audio [Red & White RCA Jacks]
Coaxial Digital Audio (S/PDIF) – [Orange or Black RCA Jack]
L/R (Stereo) Audio – [Red & White RCA Jacks]
There are primarily two kinds of audio connections you can make to output sound from your TV to external audio devices such as Home Theaters, Soundbars, AV Receivers, etc.
Digital Connection (Recommended)
Use a Digital Audio (S/PDIF) Coaxial cable to connect from the Coaxial Digital Audio (S/PDIF) [Orange or Black RCA Jack] to the Coaxial Digital Audio (S/PDIF) Orange or Black RCA Jack] on your Home Theater.
Note: If you are using the Digital Audio connection you must change the source on the Home Theater to "Coax."
Use a Stereo RCA cable to connect from the L/R (Stereo) Audio Red & White RCA Jacks] to the L/R (Stereo) Audio [Red & White RCA Jacks] on your Home Theater.
Note: If you are using the Analog Audio connection you must change the source on the Home Theater to "Analog."
Notes & Helpful Information:
The S/PDIF jacks on your TV & external audio devices could be labeled S/PDIF, Digital Audio, Optical Audio, TOSLINK or Digital Coaxial. They are all the same digital audio format which is S/PDIF = Sony/Philips Digital Interconnect Format.
In general, you would connect from a RCA jack to a RCA jack using a Digital Coaxial Cable or from an Optical port to an Optical port using an Optical/TOSLINK cable.
What should I do if I have a mismatch of S/PDIF ports?
