I have a friend's JK boardset that works except for the background audio has an issue. The first ~8 seconds of the background tune just holds a single note. After that the background audio seems normal (and all event specific audio seems OK).
I have swapped all the chips (except EPROMs) from a 100% working JH board with no change. Any ideas what to check next?
Thanks!
