Had another play today. Investigated the chainline by adding spacers and swapping nuts around to shift my sprocket 2mm and 5mm across, no difference in sound. I did this video of the noise at a low speed. That is 1Z1 chain and Planet X sprocket. It sounds terrible. The teeth seem to sit dead centre in both sprocket and chainring with a 44mm chainline measured at both points. I'm assuming it is a just bad combination of sprocket, carbon frame and chain at this moment.
