No, there never was an official patch fixing GUS sound with the enhanced CD version of System Shock.

It is possible to get Ultrasound support working: Replace the old Soundblaster and General MIDI drivers with the updated GUS AIL drivers.
This is a crude hack, which generally works, however, some users have reported buggy music when employing it.
I haven't tested this myself, it is also possible that these bugs are a result of copying the new patches over the wrong files.

Sadly, Looking Glass Technologies never released their promised patch to enable the Gravis Ultrasound support (using the Miles AIL3 drivers) for the December 1994 Enhanced CD-ROM version SYSTEM SHOCK. However, if you look closely at the low-res AVI files referenced below, you might be suprised. 😳

Gravis Ultrasound:

Low-res video Intro sample: 2.56MB AVI (2:34) (22,050Hz stereo)
Gravis Ultrasound Classic version: (Dosbox v0.65 Gravis Ultrasound soundcard emulation)

Note: This Gravis Ultrasound sample used the v4.11 release patches, overlaid with Propatches Lite v1.61, along with the 14 SYSTEM SHOCK specific custom patches. The SYSTEM SHOCK vF2.7P program INSTALL.EXE was used to play the Introthm.xmi XMIDI music.

Low-res video in-Game sample: 3.26MB AVI (2:34) (22,050Hz stereo)
Gravis Ultrasound Classic version: (Dosbox v0.65 Gravis Ultrasound soundcard emulation)

Note: The Gravis Ultrasound sample used the v4.11 release patches, along with the 14 SYSTEM SHOCK specific custom patches.

Hope this helps give you what you would have heard with the Gravis Ultrasound in 1995. 😁

Edit: Change host site to BoxStr.com

Ok. I did it!
1. Download AIL30 GUS drivers from site that mentioned above by ErikGG.
2.Extract archive wherever you want and copy files ULTRA.DIG and ULTRA.MDI to the SOUND directory.
3. Rename file ULTRA.DIG as SB16.DIG and ULTRA.MDI as MPU401.MDI.
4. Launch install.exe and select Soundblaster16 as Digital card and General Midi as Music card.
5. Save settings and exit
6. Launch cdshock.bat and enjoy GUS music 😀

The links on that site are dead, does anyone still have this driver?

The Metropoli FTP server has been around a long time, and it may just be a temporary problem. The server is actually responsive, but file transfers are failing, so possibly a storage issue.

You can get the archive here, and it generally seems to work OK with the CD version of System Shock. Make sure you have GUS patches correctly installed, and you might want to check that the IO, IRQ, DMA, and DRQ values in the game's config file are -1 for "auto" because any specific values for SB or whatever will probably not work.

FWIW, the floppy version of System Shock includes 14 custom instrument patches for GUS, and if you use them instead of the standard patches they are intended to replace, the music does sound better in my opinion.

Thank-you! got it working!
