I've got a Mars God of War where certain sounds are misunderstood.

I've tested U16 on the sound board and a couple of the channels test sounds dont sound quite right. For example Four, sounds like faour?

I think this is what is causing my sound issue, but not sure what to replace on the sound or driver board.

Any Help appreciated.

Below are a vids of me testing the board.

If U16 and U17 are good, may be you only have to turn R6 potentiometer to adjust voice speed.

How do I know if U16 and U17 are good?

Check outputs of U16 and U17 with multimeter.

For U16 outputs are inverted inputs, so if input is 0v, output must be 5v.

For U17, if one input is 0v output is 5v.

Hey there! Got a moment?
