I have installed Last express and I have trouble with sound issues. There is a constant background noise. Perhaps it has something to do with the soundblaster emulation in dosbox. Can anyone help?

I'm about a third through the game and it's happening to me too. It's constant static.

At time that happens to be as well. Usually it is fixed just by exiting the game and then restarting it. I also had a look in the manual, which seems to describe the very same thing. Either it is the CD read speed, which in this case isn't the issue, or the sounblaster emulation isn't 16 bit.

As I have said, restarting seems to clear up the sound issues.

Try messing with DOSBox's audio settings. Don't know if this'll help others, but in general, these are my sound settings for every DOSBox game. Make sure to backup the original configuration file.

[mixer]
nosound=false
rate=44100
blocksize=1024
prebuffer=50

[midi]
mpu401=intelligent
mididevice=default
midiconfig=

[sblaster]
sbtype=sb16
sbbase=220
irq=5
dma=1
hdma=5
sbmixer=true
oplmode=auto
oplemu=default
oplrate=44100

I have not managed to solve the sound issues on my computer. It gets progressively worse.

Using Vagabond's and stuboy's suggestions worked wonders for me. Solved the sound problem, and also resulted in the game running far more smoothly.

Thanks, Vagabond's and stuboy's suggestions did it

I've used Vagabond's config, however it didn't solve the sound issue.

Changing cycles=max to cycles=3000 solved it, but in return messed up the video (instead of stuttering sound, I had stuttering graphics and cursor).

I looked at the config file again and saw the line 'core=auto', so I've tried setting 'cycles=auto'. It worked - now the graphics and the sound is just fine.

So if someone still has the same problem and cycles=3000 don't work, try setting it to auto.

Just wanted to say that my sound issues (and stuttering cursor and graphics) was solved by setting

[sdl]
fulldouble=false

in dosboxTLE.conf. In case someone else is having trouble with fullscreen dosbox being choppy and slow.

I had crackling background audio.

First thing (and only thing) I tried was cycles=auto and it worked for me.

The graphics stuttered a bit for me too, and I solved it by opening the Graphics Configuration utility and changing the graphics Mode from Overlay to OpenGL. I also clicked on Double Buffering in the Advanced Settings, and now it's running the movies smoothly.
