I had a similar problem every time I set the cycles too high. The game would run fine, but the sound began to stutter. Then, when I turned the cycles back down, the sound was fixed, but the game was running slow.
Here's what solved the problem for me:
Open up the dosbox.conf file of your DOSBox and change "core" under "cpu" to "dynamic"
Code:
[cpu]
# core -- CPU Core used in emulation: simple,normal,full,dynamic.
# cycles -- Amount of instructions dosbox tries to emulate each millisecond.
# * * * * * Setting this higher than your machine can handle is bad!
# cycleup * -- Amount of cycles to increase/decrease with keycombo.
# cycledown * *Setting it lower than 100 will be a percentage.
core=dynamic
cycles=3000
cycleup=500
cycledown=500
That's what I mean. Ignore the cycle settings, just change the core to dynamic.
I hope I could help.
