I have this 2.1 set up for my work pc, http://www.fixya.com/support/p135621-boston_acoustics_micromedia_computer. It only has a single digital rca out to go to the pc, my pc only has the standard 1/8 green input. If I ran this, http://www.coolgear.com/images/SS-6FT-1F2RCA.jpg into this,http://media.digikey.com/photos/Pomona Photos/6882.JPG, to the speakers, would it work?
