I just cut up some RCA cables and made my own.
What model of genny and cd do you have?
I think, model 1 gennys AV outputs only have a mono connection. So a stereo connection for the genny has to be wired from the headphone jack.
I don't have a 32X, and havn't seen one in over 3 years so I can't recall or reply on it's wiring.
My setup is this: a model 1 genny with model2 CD
I have the stock stereo cable running from the front of my genny's headphone jack, and into the back of the SegaCD.
I plug the audio stereo jacks from the SegaCD into my stereo TV; that covers the stereo audio.
For my video I only need 1 wire plugged into my Genny. The stereo cable provides the 'ground' connection. I can't remember which 'pin' number, but it works great!
Other people might not recommend this, it might short out a TV, genny or something. But I doubt it if you're careful and don't poke naked wires where they don't belong
. It's been working great for me. and it's cheap and easy.
but your 32X setup might be a different story.
I
think if you have a model2 you don't need a separate audio cable, but with the model1 genny you do.
