I'm trying to connect my Klipsch ProMedia 2.1 speakers and subwoofer to my Samsung TV (model #UN55KU6270F). My TV only has a Digital Audio Out (Optical), and no headphone jack. Therefore, I connected a digital optical audio cable from my Samsung TV to an optical/coax digital - to - analog converter, then I connected a Y Adapter (2 RCA male to 1 RCA female) stereo audio cable to the converter. I connect the two RCA males to the converter and attempt to plug the Klipsch mini plug into the female RCA, but the Klipsch mini plug is too big! This is now the second Y Adapter I purchased and it doesn't fit into either of the 3.5mm females. Please help me. I am at a loss.
