Blind captioning on surround sound is an audio feature available with some television programs. The soundtrack is mixed with narration and vocal descriptions of the on-screen action so the blind can experience the program. On some types of equipment, special hardware is connected to the audio/video receiver of a home-theatre system to process and play the extra audio information. On other systems, the audio track can be activated or deactivated using the remote control.

Pull out the AV receiver in the surround-sound system and turn it around to inspect the back of the component. Look for a connected black box labelled with the name of the audio-captioning service plugged into a set of inputs on the rear of the receiver.
Disconnect the cable or cables by pulling straight out of the jacks on the receiver to detach the audio-captioning box, which must also be unplugged from the electrical socket. If you do not have this component, the blind-captioning service is supplied by the cable or satellite TV provider and is managed with the remote control.
Turn on the AV receiver's surround-sound system and play back an audio signal from the television.
Press and release the "Audio" button on the remote control until the blind-captioning track is shut off. You then hear only the standard soundtrack that accompanies the program on your TV.
