Quoted from RobAquinas:

I have a situation that I haven't seen come up on here with a Gorgar. I have sound and speech when I press the sound board diagnostic button. However, during game play, there is no speech. The speech board pot tests fine and is set in the middle 2k resistance to both sides. Instead, it plays sounds where there is supposed to be speech. Also, when testing the solenoids in solenoid test or grounding 10J3 pins on the sound board, sounds are played instead of speech. The dip switch on the sound board is set to 1 off, 2 on. I have tested resistance from dip switch 2 to PIA 15, and it is 100 ohms when on. I have tried several different PIAs to confirm it isn't a PIA issue. The signal going into IC 2 on the sound board seems to be the signal for sound and not speech, but I'm not 100% sure I am testing that correctly. Any advice is appreciated.

Quoted from RobAquinas:

It definitely is. Confirmed by the change in resistance on the PIA. I think it has to be a missing solenoid signal. Going to check it out shortly. My guess is Solenoid 9 is missing, and I didn't notice in test mode because Solenoids 7 & 8 aren't used.
