there is no sound at all. it only makes some loud noises. if I use a known working MPU I will hear only the voices, the music is still silent. I tested my sound board on a friend's working machine and it didn't work at first but the YM2151 was very hot so I replaced it and it worked! so my sound board should be OK but the music is always silent even with a working MPU. could it be an issue on the power pcb? any thoughts on where to start?
