That is weird, with the VXD drivers in duke nukem3d setup it should have
"Soundblaster 16 or AWE 32" @ 220 for Sound FX card and "General Midi" @ 330 for the Music Card.
There are two more things you can try.
Phils computer lab has some Livedos files at https://www.philscomputerlab.com/sound-blaster-live.html that can be used in real mode dos and MS-DOS (windows dos). You do need the Himem and Emm386 also in config.sys file, and IF you use smartdrive it has to be loaded after the sbeinit.com line.
Lastly there are WDM drivers for your card that uses Soundblaster 2.0 (NEW) with no need for (no nmi-ddma) and not soundblaster 16 for audio. These only work in windows dos. In this case, select Soundblaster 2.0 (new) in setup for duke 3d. And General Midi for Music
How to get Sound Blaster Emulation in Win9X/ME via live!5.1 with newer-current mobo's (no nmi-ddma)
With those WDM drivers there will be no emm386/himem needed and also nothing will show up in Device Manager.
I have tried all three ways with my CT4760 with success.
Additional things I could say is get the 1.5 Duke nukem 3d patch, also if you get the sound working there is a PCI soundcard patch for all the build games.
You can use something like Driver cleaner to remove all creative drivers when trying the next set. This is nice to run after you remove anything in Add/Remove Programs.
