Hi all My JM pin gives this message on the DMD on startup "soundboard interface error" I have installed the sound package which seemed to take forever but nonetheless is all there when I check it on my PC however no sound apart from the startup wav is coming through my speakers when I start a game. everything works fine if I put the old soundboard back in and I have tried reseating the cable several times when the pinsound board in situ. Any Ideas welcomed. thx Col
