I'm having an issue with the background sounds and sound effects on a Space Shuttle. The volume is always very low.
The speech works incredibly well, it's super loud! Both adjustment pots regulate the speech. I've ruled those out.
I've replaced both amps on the speech mixer board with no change.
Chris Hibler did extensive work on the MPU board. I know he changed the caps and soldered the headers.
I swapped in the speech board from my Comet with no change. I feel the issue is on the MPU side. I also checked the speakers. They are good.
At a bit of a loss. Sound is not my strong suit.
