sound's perfect on dosbox 0.74-3 from my package manager, on void linux, using pulseaudio. i manually typed in the autoexec commands and didn't set any config

Huh, then it seems like it's emulator-dependent. You could try seeing if a fresh copy of DOSBox-Staging with its default config elicits the same behavior; if it does, try playing around with the settings under '[mixer]' in ~/.config/dosbox/dosbox-staging.conf. The comments explaining the blocksize and prebuffer values mention stuttering, so perhaps increasing them would help?
