When I start a game, the voices work ok but I get no sound.
In the past I had some sound but not all ok, and the eproms were damaged, so I purchased 3 new eproms. do not know if it is linked or not as I experienced other problems, but now thete is no more sound at game start, but I get the voices.
The sound board boots ok
The test from the coin door is successful for the 8 first sounds, but it buzzes continuously at the 9th.
I read from Dave 's site that the 1408DAC generates that sound. So I replaced it. No change.
I also replaced the sound generator IC and the lm3900s. No change.
Where can this problem come from ??? Can it be from the CPU or a bad eprom ?
Any help is welcome thanks.
