I am using an Rca plug with an audio jack plug on one end (looks like a headphone jack) to connect my computer with my stereo. and i am trying to get my music library to play. because my computer speaks were destroyed when I moved house (oh yay) and whenever i start a song I get nothing but silence through my speakers I have tried restarting everything rerouting the input through my computers sub witch has an input and output jacks on it and at this point my minimal technical experiance is drawing to a close and I would appreciate any help I could get.
