I have a problem with my system, id like to connect my computer to my tv to play the music from the pc on the speakers in the tv. But i cant seem to find how it works. Since I dont want the videopart ( its not neccesery) only the audio. Preferably via the PC audio in or or the composite since the optical is already being used. Ive tried to connect in a multitude of settings but cant seem to get it to work.
