It's difficult to work out without hands-on testing...

Try the Creative Labs patch from this site:

Newer sound blaster cards may not appear the same to programs as the originals from the DOS era; old software assumes each program can directly access all the machine hardware, while the newer standard assumes all software works via the system drivers and "user" programs do not have any direct access to hardware devices.

Unless the whole machine is from the correct era, it may just not work...

Alternates are using a newer executable such as winrott (info here)

Or an updated version such as supplied by Gog.com
They are both "The original game", the same game data etc., just an updated executable that can work with more modern hardware.
