Walter Lord has set up (and still maintains) a home page when the Ensoniq Audio PCI came out: http://www.netexcite.com/audiopci/index.html You find lots of drivers, the 8 MB wave table sets for the Windows driver and other useful information there. Wish we could use that wave tables for a midi device.. To make a long story short. The original Ensoniq Audio PCI card used the ES1370 chip (PCI & control) and the AK4531 codec for AD/DA. Later they made Audio PCI cards with the ES1371 chip. This one seems to be able to use lots of different codecs (that is where the driver fun comes in) that comply to some Intel spec (AC 97), among them the AK4540. All this time, Ensoniq also sold their chips to OEMS, who in turn might have used the same codec or even other stuff. Then Creative came up and bought Ensoniq to get some decent PCI card. The PCI 128 seems to be more or less the same like the Audio PCI (I am not 100% sure, because the latest greatest Win drivers do not work for me anymore), the PCI 64 is reported to have at least a lesser quality code. And more fun: recently people reported an ES1374 chip - I have no clue yet where this one is different.
