I had an issue with my FP where the speech board would kill the sound board completely,
sound board would work ok by itself if jumpered, remove jumper and plug in speech board nothing but silence.
I decided to remove all the speech roms and plug the bare speech board back in to see if sound worked,
it did.
Turned out Ic7 rom was bad and killed the sound completely,must have been corrupting the data
got a new set of speech roms burnt all good...
Had also replaced all the sockets etc for good measure...
