The sound trigger is hairy, i checked the grounding straps, all in tact, all measure .000001 ohms back to earth point.

The sound trigger is also triggering the normal (bell/chime) sounds when in fact the rom is in "synth" mode.
I manually flick every switch on the playfield and can't find the same sound that the flipper triggers, but when i switch the soundcard into normal mode (not synth) i hear the same sounsd on various targets etc.

weird.
