OK folks, this one has me flummoxed.......

I've got a Pac cocktail - Plays great, etc....The problem is, I'm not getting any sound. I've tested the speaker - it works. I have the proper voltages on my edge connector....My original board had a couple of shot ICs in the sound circuit, so I replaced those - still no sound. Figuring my board troubleshooting skills were not as good as I thought, I went with the nuclear option and bought a new board - stuck that bad boy in and still nothing.

So, to sum it up:

No sound
Speaker good
Voltages good
Board good

Any ideas?
