I have tried lots of PCI sound card in my computer (Ryzen 3900X/Biostar X470) and they all work perfectly fine in Windows 32bit:

Aureal 8820
Creative CT4740/ES1371/5805 (I use this for Windows 3.11 - with 3rd party drivers)
ESS1938s
SB Live!
M-Audio Audiophile 24/96 (works from NT 3.51 to Windows 11/64) -> In NT 3.51 and 4 - not so good compatibility with Unreal, Quake II.
ALS4000 - this one has good working drivers for NT 3.51, including sound in Unreal, Hexen 2.

DOS is a different story for AMD boards. Aureal 8820 works on a Haswell configuration with an ASMedia 1083 - but not an AMD X470 with the same bridge chip. AFAIK AMD chipsets are not getting any sound in DOS since AM3 socket...

I'll will try a PCI-E to PCI bridge with subtractive decoding support, not all PCI-E to PCI chipset bridges have support for this.
