Do you have a source for this? AFAICT this is untrue. Mono audio using just the white connector exists, but this depends on configuration and does not make the red connector a difference signal.

I swear that I’ve seen it mentioned somewhere, but you are entirely right that I can’t find a source. Maybe it was some weird device I used a long time ago? Regardless, sorry for not doing my research before posting
