S-video was a mini DIN connector which wouldn’t have fit into one of these RCA jacks.

If you’d put composite video (the yellow RCA cable in this setup) into one of the audio jacks, pretty much all TVs would not do anything with it as an incompatible signal. If they actually tried to turn it into something, it wouldn’t be audible. Composite video generates a signal at something like 5-10Mhz, human hearing tops out around 20Khz (250-500x lower)
