So, now that the game's playing correctly, it's time to get back to the sound.
After it got fixed, there'd be no sound for a couple hours & then the gameplay music would play constantly. Then odd sounds would start, like the explosion sound would start & then become constant. Turning it off & then on or pressing the reset on the soundboard would make it stop, but it would eventually return. No sounds would play during switch hits or when starting the game or when it counted bonus.
Last night the music started, but it would also play the machine gun sound when it spells Raven at the start of the game & when counting bonus. Surprisingly, it would also play sounds when switches were hit. Maybe not all switches & maybe not the correct sounds; I'll have to watch a gameplay video to refresh my memory. It definitely played sounds that didn't belong. Plus, the gameplay music kept playing beneath the sounds. Switching it off & on & pressing the SB reset wouldn't stop it this time though.
The tech was going to try to find a soundboard to try in it, but now I'm not sure it's the SB. He's a half hour to 45 minutes away & I don't want to get him here if it's not. I was new to electronic troubleshooting & repair back when this started & I messed with the A6P1 connector with the game on. Would this corrupt the sound proms? I'm leaning this way. I honestly don't think it's a connector, but it may be the driver board too.
