I've managed to completely fix my sound stuttering issues using the following config options.
You'll need to edit either dosboxMOO2.conf (for normal use) dosboxMOO2_server.conf (for multiplayer games as host) and/or dosboxMOO2_client.conf (for multiplayer clientside games)
[sdl]
fullscreen=true
fulldouble=false
fullresolution=original
windowresolution=original
output=ddraw
autolock=true
sensitivity=100
waitonerror=true
priority=higher,normal
mapperfile=mapper.txt
usescancodes=true
[render]
frameskip=0
aspect=false
scaler=none
[vsync]
vsyncmode=on
vsyncrate=75

That fixed your sound stuttering issues? Usually the fix for those is setting a larger sound blocksize and bigger sound buffer. Those all look like graphics settings.

It works. My system is WinXP.
Oddly enough, changing graphics renderer to Direct Draw fixes things.
This section needs to be added to the file manually, as it's not there:
[vsync]
v syncmode=on
vsyncrate=75
Please take care to ascertain what's your monitor's refresh rate. For mine (as with most laptops) it's 60Hz (not 75Hz) and put the appropriate value.
Good work Dan!
