I recently purchased a broken Sega CD Model 1 off an auction and did a bunch of small repairs. So far I've gotten everything to work perfectly except one annoying problem that I can't seem to figure out, stuttering choppy audio. All of the obvious things have been checked & contacts have been cleaned thoroughly and the Genesis runs fine on its own. When connected to Sega CD the sound is stuttering from the Genesis headphone port as well as the TV and even when the mixing cable is used. The only time it sounds clear is when a aux cable is plugged into the Sega CD mixing jack with nothing connected to the other end, which I assume is disabling the sound that is coming out of the Sega CD side of things. Anyone ever experience this before?

The laser is probably dying.

I had choppy sound coming from a Turbo Duo and it turned out to be leaking capacitors.

Check the caps around the audio circuit for signs of leakage and replace as necessary.
