I recently build a new retro machine and encountered a very strange sound problem with Rayman 1.
When I run the game as soon as I enter the main menu, the PC speaker constantly produces buzzing noise.
It almost sounds like an old harddrive on read access and it does that through the entire game until I exit to Windows.

The system:
ASUS SP97-V (latest patches BIOS)
Intel Pentium MMX 233
64MB RAM
S3 ViRGE/DX 4MB + Diamond Monster 3D Voodoo 1
Sound Blaster 16 CT2230
Windows 98SE

Things that I already discovered:
- Rayman 1 v1.0, v1.12, v1.20 are all affected - Tried them with the original CD, BIN/CUE and even with NoCD patches.
- Activating or deactivating the music in the options menu does not resolve the problem.
- Running the game under DOS reduces the amount of buzzing noises, but they are still there.
- Changing the soundcard does not resolve the problem.
- Changing the sound driver does not resolve the problem.
- Changing the PC Speaker on the mainboard does not resolve the problem.
- The PC speaker works perfectly fine with other games.
- Rayman 1.0 NoCD works fine when I copy the folder to my other retro rig (P5A, K6-III+, Windows 98SE).

So, I am completely out of ideas here and would love to hear your suggestions.

It sounds like it might possibly be a hardware conflict issue?

Rayman is the only game that's problematic, but I double check it later. 😀

The configuration seems to be okay, so no obvious hardware conflict. 😒

Rayman 1.0 NoCD works fine when I copy the folder to my other retro rig (P5A, K6-III+, Windows 98SE).

If I remember correctly, Rayman uses CD audio. Do other games with CD audio, e.g. Quake, have the same issue?

The other thing I was thinking that it could be a bug in the HMI drivers that are part of Rayman (MHIDRV.386 and MHIDET.386). Not sure who developed those but if you can think of another game using those drivers, maybe that game also has the same issue?

I was also thinking CD audio having something to do with it. Does the music even play?

HMIDET and HMIDRV, but yes. Some other games using these are Brutal: Paws of Fury, Super Street Fighter II Turbo, Descent/Descent II and Tomb Raider.

Sorry to bring up this old topic again, but I haven't had much time over the past few months to deal with the older systems.

In the meantime, I managed to buy a second ASUS SP97-V with the same revision 1.02.
I've now run a few more tests and was able to determine that the motherboard is the culprit.

Using the new SP97-V motherboard, I built an entirely new system with different components and used Windows 95 instead of Windows 98.
The error appears here as well - whether the Rayman CD is inserted or not makes no difference at all.

So it must have something to do with the motherboard, since everything works perfectly on all my other systems.
Very strange.

Someone here with a SP97-V mainboard to confirm this?

I bought an ASUS TX97-E motherboard and rebuilt the PC. All components remained the same - only the motherboard was replaced.
The issue has disappeared. So it really does come down to the ASUS SP97-V.
