I have a space shuttle that has no sound. I have the proper 12 volts coming off of the power supply. Where should I test on the MPu to ensure there is 12v at the sound section? I can confirm that it is not the speech board because I swapped in a known working one. I can also confirm it is not the PIA for the same reason.
I have an entire system 11a board with a clean sound section I can scavenge parts from. What do you suggest I change?
