Sound jittery in Johnny Castaway
I made sure I followed all steps as instructed. When finally starting DOSbox, JC starts after a couple of seconds, but the sound is "jittery" A bit difficult to describe, but it is like it starts to play a sound like the "huh"from JC and repeats the first 0.2 seconds over and over until there is a next sound, and then it will do the same on that sound. I comment out the lines
#win runexit c:\windows\scrantic.exe /s
#exit
and started DOSbox again. Then when I start win, I se Windows 3.1 starting and it does that continuously. I guess either windows 3.1 or the sound settings have a problem.
Any clue?

Hello Aryan,
Here are two things you could try:
Re-open the DOSBox Options file and find the "prebuffer=25" setting under [mixer]. Change the value from 25 to 80, save the file and start DOSBox again.
If that doesn't solve the problem, change the value back to 25, scroll back up a bit to the [cpu] section in the options file, then replace the following settings:
core=auto
cputype=auto
cycles=auto
cycleup=10
cycledown=20With:
core=dynamic
cputype=auto
cycles=fixed 40000
cycleup=5000
cycledown=5000Then start DOSBox again. If you still have the "win runexit" and "exit" lines commented out, see if you still hear that sound continuously. If you do, use the key combination Control + F11 to lower the number of "cycles" dynamically. Keep pressing it until the sound problem goes away, it indeed it does.
Hopefully one of these things will solve the problem for you. If not, let me know.

Thanks for your quick reply.
I tried both options to no result. I only know that the problem starts when I do
cd windows
win
Immediately after the Win 3.11 logo disappears, the desktop appears and a fast repeating beep sounds continuous until I close windows. I believe that beep is the first 200ms (or so) of the Windows startup sound.JC seems to play at a normal speed.

After some searching the internet I found a simple solution.
In the options file at the end there is an [autoexec] section. I added the following line.
SET BLASTER=A220 I5 D1 T6 H7 P330Making sure the numbers correspond with the [sblaster] section.
Hope this helps for others too as I understand the stuttering sound happens with a lot of people as I believe the SET BLASTER line is missing from [autoexec] section.

Glad you could resolve it on your own, Aryan, and thanks for sharing the solution!
