Perhaps it’s a matter of setting a whole byte instead of bit masking a single bit and leaving the others untouched. Programmers can be lazy and from the developer’s perspective “it works, right?”

Could you maybe give us a little more information about your AUTOEXEC.BAT perhaps? And how the jumpers on your card are setup? It seems odd that the ULTRASND variable is rejected if you only changed the port address.

Bit counter productive to have it set at that by default though. No, not really. The CD input can be very noisy depending on the cable that is used, the path it takes and the rest of the environment. Setting the CD input only active when it is needed eliminates a lot of constant noise, especially …

The Interwave cards like the GUS pnp provide one DirectSound voice on the codec and 4 additional DirectSound voices on the synth chip in Windows 98. That way you can play a mp3 file and hear the annoying navigation sounds all at the same time 🤣. There is a catch, though. All that data has to go over …

I just tested them, and Amnesia does actually work, but you need to boot without memory managers. That is, also without HIMEM.SYS. It doesn't seem to like those. I thought that I had Saga working, but I forgot in between testing to use my PicoGUS instead of my real Sound Blaster. Whoops…

It isn’t exposed because during manufacturing the pins of the IC package embedded in the clock “module” are bent up. Then the crystal and battery are soldered to the bent up pins and the whole thing is potted in resin. That is why some of the pins are seemingly missing. You can also see this in some …

Unrelated, I maybe found a bug or difference in the GUS mode when using Open Cubic Player (latest version, 2.6.0pre6). When I play a song of my own (happens to be the first in the directory) it starts at least some instruments "late" or it fades them in. I notice this because they are very short, …

After some sleep 😉 and pulling some more hairs, I finally managed to get the Amnesia demo running again. Aaaaaand… there was no latency on the sampled instruments. Soooo, this is a Scream Tracker thing. It seems there are more problems with Future Crew software. Second Reality crashes when you want …

The Speedsys memory benchmark still seems very slow to me. My socket 3 board (when running @33 MHz) does ~48 MB/s on L2 cache speed vs 24 on your board, and memory throughput is 31.12 MB/s vs 20 on your board. Also, VESA (?) memory speed (left above) is 6947 kB/s which again seems slow compared to …

I think the PicoGUS has a slightly lower output then say a Sound Blaster (even in line level mode). I have it connected to the line-in of my AWE64 and I have to crank the input all up to make it audible. If I connect the PicoGUS directly to my mixer I have to increase the gain quite a lot to reach …

You have to be aware that often those DVI outputs are fixed at 60 Hz so software that waits on v-sync may run too slow. It is the case with my MX440.

I don't know the actual implementation of the GF1, but I did some software synthesis when I was in college. Basically, when you have a wavetable or sample based music system, for every channel you keep track of the position of where you are in the sample. Each output cycle you update your position …

If you have the space I’d run them side by side. For me this works fine, I can have SB16 and AWE support, hook up a PC speaker, and at the same time have support for almost every other sound card ever made. You’ll have to figure out the resources (IRQ and DMA) but it is doable with 2 cards.
