A:Answer It will work if the 3.5mm jack is an input. But, if the jack is labeled as a headphone jack that means the sound is coming out, so it’s an output. If I’m looking at the right model, it looks like the only input on the Soundbar is an optical port. If this is the case you may need to loop the CD player through your TV if your tv has both RCA jacks in and an optical out. Or I believe they make RCA to optical converter boxes.
