Sound on S100102

[Mat-Moo]

So I have a square S100102 pump 6 wire connected to a pcb V2B - I believe all configured correctly, but struggling to get any sound. Latest firmware (Compiled and uploaded today) - Looking around it could need different voltage? But what do I need to change on the board setup/config

Hi! I don't know. It seems there is a different circuit on the newer pumps.
