I've been following this thread for some reason, and I finally figured out why. I think I had a similar "multimedia PC" my parents bought for me about 20 years ago (486SX 33MHz, 4MB RAM, 200MB HD, 2X CD-ROM and Sound Card when these were still considered optional, DOS 6.22/Windows 3.11). And I remember getting Front Page Sports Football Pro 95, Wolfenstein, and Doom working on this.
Anyways, someone on VOGONS did a ton of research [0] on similar sound cards. I suggest reading it.
