I want to keep the soundworks 4.1, but the 3.5 mm have me either not using toslink and enjoying the options for sounds on my motherboards, or have to buy conversion cable from 3.5mm to rca on both ends of the cables. Computer end and speak end. Though there is a box I can run this 5.1 cable adapter on Amazon Wiistar 5.1 Channel AC3/DTS Audio Gear Digital Surround Sound Rush Decoder HD Player with USB Port ($25.00 USD).
Since I purchased these speakers new a long time ago, they just though we would be happy with 3.5 mm connectors into the sound cards or pc's. Yes, they are old, but still work great. But, I am losing out on a much better sound experience if I can go through the Toslink and RealTek equalizer.
