I noticed in Ganryu (Neo Geo), there is a noticeable click/pop sound when slashing, and in a few other places where it is a little less noticeable. This does not happen on real hardware (I own the game and 3 MVS boards and can confirm). It also does not happen on FinalBurn Neo, which uses code derived from the old MAME YM2610.
My recording using my Neo Geo emulator (Geolith):

This uses an admittedly very modified YMFM, but it sounds the same in the most recent MAME revision I am able to build on my musl-libc system (0.256).

I hope this is enough to begin a diagnosis.
Thanks!
