I have directv incoming From there the signals go to my Marantz amplifier, where the sound goes out to my Bose sound system and the video signal goes to my TV. I have tried plugging into the various units, but the ports of connection don't match to what you say to look for. The tv only receives a video signal and the amplifier sends all of the audio to the Bose unit Now what do I do?
