    Inaccurate meme - the white and red RCAs in composite typically don’t actually carry the left and right channels - usually, the white one is L+R, meaning both the left and right channels combined into one, and the red one is L-R, the difference between the right and left channels.

    This is done so that a mono television, which will only have a yellow and white port, will still be able to hear both audio channels, as opposed to having to completely miss out on one of them

      • It’s so funny, I had the same reaction! Never quite understood it, just switched plugs until it worked. Then it got phased out and… decades later a meme brings light to my confusing childhood!

      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

          The signal in fm radio works like you described. Poor fm, declassified to just some weird device :(

        It’s possible that it might only be a thing in PAL regions - I’d try, but I don’t have anything that uses composite to try now.

          I can confirm that everything that uses component and L/R that I have used in my life (born in 2001 in the Netherlands, so PAL) has separate L and R channels. I have confirmed this with my multimeter before.

        I use those on my speakers and I can flip left/right stereo if I flip the cables. I think that confirms that they don’t have both in one I think.

      I appreciate you starting this comment with ‘Inaccurate meme’. I think it should become a thing. Really helps me know to buckle in for something good
