Is there a way to bypass the amp and hook it up to a speaker? I am just curious as to why its just that one sound especially the lowest digital sound.

My plays great every sound works except one. At the very beginning when Kong climbs up the ladder and jumps the girders move and he smiles your supposed to hear 3 beeps. Mine sounds more like a muffled sound rather than the 3 beeps. Its also happens after Kong grabs the princess and goes to the next level. Every other sound is fine.

Here is what I have done. Replaced Audio board, replaced all the sound caps on the board and the Q3 transistors. I also got a new Audio chip and replaced LM cant remember the number.

I dont know what else to do. Its not a big but my OCD wont let me leave it go.
