Possible Solutions

Verify that the MUTE button on the cable terminal or the remote control was not pressed. Press MUTE on the remote control to restore sound.

If the cable terminal audio output is connected to the TV, verify that the MUTE button on the TV was not pressed.

If the cable terminal audio output is connected to a home theater receiver, verify that the receiver is set to the appropriate input source and the mute button on the receiver was not pressed.

Verify that you used the correct audio cables for the ports.

Verify that the audio cables are firmly connected between the cable terminal and the audio playback device (TV, receiver, DVD player, etc.).

Not all Dolby Digital programs feature full 5.1 surround sound. In some cases, the programs may only contain left and right stereo audio.

Verify that the coaxial or optical SPDIF cable is firmly connected to the cable terminal and the home theater receiver.

Verify that the home theater receiver is set to a surround sound audio mode (Dolby Digital, Dolby Pro Logic® II, or Dolby Pro Logic).

Verify that the receiver is properly configured to work with all connected speakers.
