Recently received a scramble PCB with no sound. Found the data pins on the 2114 RAM at 6C & D were giving weak signals so replaced them and the sound came back.
However. theres a volume issue; some sounds seem to be much louder than others, and it seems random which are which, IE sometimes your bomb will be quiet, other times loud. Its the same with explosions and even the background warble.
Ive swapped out the ay8910s which made no difference. been trying to work out from the schematics whats up and not getting very far, taking a break atm so if anyone's had similar problems please lmk.
