Methods and apparatus for managing audio corresponding to a video stream in an audio-visual system are disclosed. The audio-visual system includes a display capable of simultaneously displaying two or more separate video streams, and sound reproducing devices intended to deliver audio to viewers. The method includes receiving an audio-video signal comprising various channels. Two or more channels are selected for viewing. The audio associated with the selected channels are identified. The viewers who want to watch the displayed channel are identified. The sound reproducing devices associated with the intended viewers are also identified. The identified audio streams are then directed to the identified sound reproducing devices such that only the viewers associated with a given channel can hear the audio associated with that channel, to the exclusion of other viewers.
