OK I'll test the low quality MAME version and see how it measures up
performance-wise. The problem is I don't know how to compare the sound
quality vs DOSBOX.

Still, only Scumm games seem affected. The music in Scumm is VERY
soft, almost inaudible. PROP_OLD_ADLIB affects some values in the
volume calculation, and I wouldn't be surprised if the problem is that
whatever values are used don't work well with the DOSBOX adlib driver.
