Exactly. I use the SBPro2 and SB16 setup because I do comparisons and experiments so I use the authentic cards, but individually they are incomplete. Audician 32 on the other hand is the best (IMO) and most complete card for a single card setup in a DOS machine. The only caveat being missing ADPCM …

Fair enough. What about PTS-DOS then ? It was very speedy (+286, 100% asm!) and later versions supported FAT32, too. https://en.wikipedia.org/wiki/PTS-DOS I had been planning to perform compatibility testing for a while but sidelined the project for other, more pressing matters. I've always wanted …

Thanks, I think I've found out the culprit. The PCB reads Raspberry Pi B+ v1.2 . Seems like I got the B+ instead of Pi 2.. Visually they are quite similar and since I have never taken the case apart, I didn't notice (got it as complete "Pi 2" set). Oh, well.. But so is life. *sigh* Anyway, thank …

Yup. I'd even go so far as to say that HIMEMX is at all levels superior to MS-DOS HIMEM, but EMM386 is sometimes required (because of port trapping, for example).

FreeDOS is fine, but last I looked it does take a small amount of tweaking to have all the tools and utilities in place for maimum compatibility. Key items include HIMEMX, JEMMEX/JEMM386, EMM386 (MS or PCDOS version), CD-ROM drivers, network drivers, and sound drivers. PC-DOS 7.1 is also very useful …

It would definitely be a tricky project. I had considered output impedance on the port, although I wasn't sure if it would be surmountable. Different logic levels would make it even more of a tangle.

It's an ESS Allegro chipset, so it's ESS' PCI sound technology. Although it doesn't provide true ESFM like a Solo-1 does, Iit should use the same sideband technologies and therefore be quite compatible with DOS -- much more so than a SB PCI/Live card.

I mainly referred to AbandonwareGuy's initial statement, the 8800 series will yield similar prices than a V5 5500. I highly doubt that. Not only were they produced in much higher quantities, they don't really stand out that much. They were good graphics cards but they didn't revolutionize anything. …

You'd be able to drive anything compatible with the voltage swing and max current supply of the opamp. Generally, that includes line level inputs and some headsets. Any speakers or headphones which demand higher voltage or higher current from their supply would need another amplifier in the …

That's essentially what the opamp does for you (within the current draw limits of the chip of course). Low output impedance from the amp prevents any line in from being attenuated.

But the output of the DAC would still be too low to drive a line-out, headphones or speakers, right? In which case you'd need another amp for that. But if you were to connect the resistor ladder to such an amp, you'd get the same advantages of buffered output and stabilized/consistent output anyway …
