The optical jack is designed to output sound when the video you're watching contains digital audio (PCM or Dolby Digital® technology). This feature is available on certain digital broadcasts and streaming videos and isn't supported on standard cable or analog stations. If the video doesn't contain a digital audio signal, you won't hear sound through this connection. In this case, you would need to use a secondary analog connection to pass the audio signal. The sound sent to the TV through an HDMI® connection, or other input, may not output through the optical jack. In this case, you should connect the optical jack from the source device (Blu-ray Disc™ player, DVD player, etc.) directly to the home theater or stereo system to get sound.
