I updated my VB scripts to the latest.
I tried deleting the NVRAM files, and no luck.

My versions are:
Visual Pinball (0.4.1930)
Visual PinMAME 1.10 (release)
VB scripts 2.33

It doesn't seem to be anything with sound at too high of a volume either. I have used the same sound settings between the 2 versions. But just as a goof, I lowered the volume in the Visual PinMAME interface (hit ` and adjust the dB), but no luck.
