The CD audio sound buffer isn't part of the PCM buffer DOSBox outputs sound with.

Ok I was nearly sure it was a problem with the audio cd feature, but now, how to get this sound in the video.

Hm maybe try it with a cue/bin pair mounted with imgmount, that grabs the
audio data in a different way. Don't know if it's recorded that way though,
maybe somebody else already tried it.

I'll use another capturer that captures only sound in the same time and then mix both video and sound, in waiting a better solution.

See above.

I don't fully understand the OP's problem, but it seems he (or she) is trying to capture video with DOSBox, and doesn't get music in the captures, although it's playing during the capture.

WCII has CDDA and MIDI soundtracks, AFAIK. I don't know if the CDDA music is captured (the OP should try what wd has suggested), but i'm quite sure the MIDI won't be captured, because it's played "outside" of DOSBox, by whatever MIDI device Windows is configured to use. The solution would be, as the OP already has noticed, to capture the music with a different capture program, and then mix it with the captured video.

Hmmm... Why am i writing this? (;

Ok but how i create the iso ?

Ever head of Google?

If you create an ISO you won't get cd music

You will want to create a BIN/CUE

I meant... with DosBox.

Why this difference?
Can DosBox do it or I need another program to do it?
Which one is the best?

I meant... with DosBox.

DOSBox is a pc emulator and no iso creation utility.

Why this difference?

Because the iso format doesn't store audio tracks per definition.

Hmm.. that's why there was not music with .iso cd.. (with audio tracks)

Which iso creator (cue/bin) is the best?

Doubt there is a best.

IsoBuster works.

OK I did and I managed to reproduce one thing I've done I don't know how without the .bin : Having strange music, it's the music, but played in a different way, like real MIDI ^^ this is recorded, but on the non bin I have both Sound Blaster for sound and music set, and on the bin one too, but the music is not the same 😒 why?

Finally I use DosBox in normal mode and I capture the video with CamStudio and all the sounds and music are ok.

With CamStudio capturing the DosBox window, I take all the music as it should be, here is the produce :

You could have just set your sound card to record what it outputs then use Microsoft Sound Recorder >.>

When you record using Dosbox you get bitperfect output and even if Dosbox chokes because of the lack of CPU time, the recorded output won't have any of that.

If you record video and audio separately (with the audio being recorded by a separate piece of software), they would easily go out of sync, because the recorded video won't have any video drops resulting from the lack of CPU time, but the audio will have.

Finally I prefer my answer with CamStudio, I don't need to do other work of mix, and I use the same method but with Virtual Box for Starcraft.
It's strange because the sounds are not the same with War2 installed on a Virtual Box machine.
