I've tried to dissect my previous FreeDOS instance where it worked.
Turns out, it used SHSUCDX 3.07 and UDVD2 4-30-2013, so these are the
package versions I installed. Unfortunately, it didn't work. It's still
playing static. I have also disabled the second CDROM sitting on the
same IDE channel, just for extra safety. Still nothing. I don't know
what to do anymore. The only option I see is reverting to FreeDOS 1.2
and importing the relevant sound card drivers there.
However, this setup works flawless in Windows 98. Tried it with "The
Sting!" which relies on a CD soundtrack. Maybe the options with which
the drivers are loaded are different?
BR,
Michał

I used this version of OAK

and the problem persists. I even tried 3 different sound cards with
the CDROM in UDMA and PIO modes:
- SoundBlaster AWE64 Gold
- SoundBlaster Vibra 128
- Yamaha YMF724
It took me this long, because to avoid messing up my system, I have
added additional modes the system can start with, besides the basic 5
present in FreeDOS 1.3 RC5. My extra modes are specific for each
sound card with extra /K parameter for COMMAND.COM
<http://COMMAND.COM> so that the drivers are up and ready as soon as
I receive an interactable console. I also needed to edit the Yamaha
driver to add support for the southbridge.
In all 6 tests, the CD input would produce static noise, except with
Vibra 128. Don't even get me started on this card, it's always been
an unstable mess in DOS, courtesy of JEMM386.
Any more ideas? It used to work flawlessly in FreeDOS 1.2 with
SHSUCDX backported from 1.3 RC that was newest like, at least a year
ago. It turned out back then that SHSUCDX from FD 1.2 does not
support CD playback at all.
There are 3 versions at
https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.2/repos/pkg-html/shsucdx.html
Version 3.08 & 3.08a are the same, with just NLS updated. However,
there is also 3.07 and 3.05.
You could try the middle one.
So, where did things go wrong? Could it be possible that between
FreeDOS release candidates, SHSUCDX changed to fix the issue and then
break it in a new way?
Best regards,
Michał

Not sure about the circumstances of your Rayman crash but I’ve read
many posts about issues with that game on DOS. Apps that access the
file system or hardware directly, disk caches can cause certain
types of file corruption. Whole file system corruption is odd and
might indicate other issues (CPU, RAM, IDE controller, BIOS, drive).
You haven’t provided any details about your hardware. That said,
most drivers had compatibility with multiple drive makers. And
usually, you only had to specify the device “/d:xxyyzz”.
There’s a list of popular device drivers here.
https://www.hiren.info/downloads/dos-files
MS used to license OAKCDROM.SYS and CD1.SYS for IDE drives. You can
find other cd rom drivers at
https://www.allbootdisks.com/disk_contents/98.html
I’d try to find your vendor’s driver disk in archive.org
<http://archive.org/> or other vintage computing sites.

After working with Rayman I am simply traumatized by crashing
anything
under DOS, because any and every crash can mean the destruction
of the
filesystem's integrity.
I'll try and get the OAK driver and let you know what happens next.
Best regards,
