Some how our church youth building had the audio from the hp computer streaming to the Lg stereo system and picture from the computer on the tv. The tv stil has the picture, but the stereo is not playing the audio of the videos. There is a cord with yellow ends and i plugged the one end into the digital audio of the computer and I am not sure where the other end is supposed to go into the stereo and I dont know if I am missing a cord or something else that is supposed to connect. Thanks.
