Hi
I have now got a andy capp working, and all things was working inc, the sound, but i had to test some more mpu 4 boards an prog. moduls on it. and now when i put the first mpu back inn, all thinks works except the sound. ( i get the same thing ting if i change the mpu With a other that are working ) So i have a working Road Hog so i tested the Andy capp prog modul on that so i know that the sound is in working on that macine. so any one have som tricks here? So the proga Board whit all the andy capp proms, Works With sound on Road Hog but not on the Andy capp machine, still i have tried With to working mpu 4 Boards, and i have also tested the wiring from a-b. Or may it be that booth the mpu 4 Boards have a damage to the sound now ? 
Thanks
