It is so low and barely audible I'm not convinced the original PCB output didn't do the same thing - just you never hear.

You can compare it with Final burn alpha emulation, Original soundtrack or the real pcb like I did. This is a mame issue.

FWIW the crackles are produced by the "oki2". It can be checked by reducing its volume to 0 via sliders.

to my ears they're there in the original recording too, just mixed in at a lower level, I think it's meant to be percussion?
