A small audio project I am doing is producing mono audio right now. To stop annoying my family I added a headphone trs socket as an alternative for the (single) speaker. audio (-) is wired to the sleeve and audio (+) to the tip and ring, so that I hear it left and right. Unfortunately the signal on the left is coming out relatively quiet.
Should it work this way? Or should I just add a mono trs socket and the headphones will do the right-thing (TM) and duplicate the tip signal?
