switch c and d

Wow. Thanks a bunch, that worked wonders.

Another question though... there's no BGM? Sound effects work though, and I used autodetect at installation, and the sound test there worked... sorry if the question's a bit stupid, I'm kinda new to this. Thanks again.

GUS emulation can cause problems in some cases.
Open dosbox.conf (inside your DOSBox dir), look for the entry GUS=true and set it to GUS=false. Save the file, run Rayman sound setup again and select Soundblaster 16 for music and sound effects.

Nope, didn't work. Any other ideas?

have you tried adding
-usecd 0 -ioctl to the mount d g:\ -t cdrom line ?

Yes, just tried that. Nope, didn't work. Any more? Thanks in advance!

Have you tried to uncheck "Mute" (cd) in Windows volume mixer?

There isn't anything muted in Windows Volume Mixer...

Did you configure the music stuff? How?

Well at the setup menu there's a sound option. I used autodetect and it stated Sound Blaster Pro 16 and some ports... so I ran the sound test (all included in that menu) and heard Rayman saying "Perfect" indicating that the sound was working properly... and so it does. There's just no friggin' background music, only sound effects.

Check for midi or something, port 330.

The setup seems to hang if I manually select any other soundcard... pretty weird. Couldn't find a midi something by the way, but I tried a few others, and setup would hang with all of them except the SoundBlaster Pro 16 from the autodetect...

Sounds like digital sound device.
Maybe check the manual if the game supports midi or cd audio.

Rayman1 background music is from the CD audio tracks, not MIDI.
Rayman1 sound setup does not decide whether rayman will use the background music or not. It only allows you to choose the sound card type for the effect sound.
In Windows Volume Mixer, "CD music" might be hidden. Go to options menu, check all the items including CD, and uncheck "Mute" on the CD music.
If it still does not help, try to convert your original rayman CD to an image (BIN/CUE) - there are some converting tools like UltraISO that will create the image. (If IMG is used instead of BIN/CUE, an external utility like DAEMON is required because mounting the IMG in DOSBox does not play cd audio.) If everything is fine, type (if rayman.cue exists in c:\download and you want to mount drive E as the imagefile):
imgmount e c:\download\rayman.cue -t cdrom

Thank you very much, the image worked. I had the same problem on Windows Vista. With Windows XP the original CD always worked. But it's important that you mount your image first before you mount "c:\program files" as drive c because then dosbox looks for the image not yet on c:\ but on c:\program files.

Specs say that under vista the ioctl capabilities have been reduced to a
bare minimum, but i haven't gotten any confirmation for this yet.

Maybe...
When I mount the original CD as drive d:, I can see the continuous flashing of the CDROM-drive's LED, but I can hear no music.
Maybe you can describe this procedure with the image in the readme files of future Dosbox versions...
But still Dosbox is a very great emulator. Thanks for programming it!

The procedure? Well create a cue/bin pair, and mount that. The latter part
is in the readme already.

sorry, my English isn't perfect 😊 , in German you can use "Prozedur" not only for a very long process...
I simply meant a sentence like: If you want to use CD-Audio-Tracks with Windows Vista, you must create an image and mount it.
