Summary	06780: Possible Volume balance Issue with Williams Adpcm Soundboard
Description	There has been discussion for quite some time about games like Mortal Kombat having either too load dac/not load enough fm. I couldn't find direct pcb capture of that game, but may have found capture for NBA Jam that runs on the same hardware. The description says the game was captured from a jamma board. Comparison video from 192 with volume sliders at default levels: Mame capture is short because I don't have much space left.
Steps To Reproduce
Additional Information	Marked as trivial because I could be wrong about this.
