Finally got my Haunted House back up and running except for sound, which is intermittent at best. Pulled edge connectors, cleaned and replaced. Nothing seemed to work. I first attempted to bring it back using old boards and then replacements but ended up pulling them all and using PI-80 which solved a ton of issues and gave me fantastic diagnostic help to move forward but the sound issue is persistent and I am reaching out for ideas to debug. If you can point me to a good thread or drop some responses I'd appreciate it.
Figuring my next move was to replace the old sound board but with the new FLIPPP version but trying to avoid that if possible. New speech sounds neat but I really just want my classic sound back.
