Ah. nasty.  Yes this is what I have.  The Creative (marketing) card.
Ironically the PCI64/PCI128 cards would have been easier to get. I
could have saved a two hr trip and only paid a few dollars more.

I did find a pair of linux drivers for both the es1370 and es1371 .
Much of the framework for the files is the same, with only 268 diffs
under emacs' ediff. ;-)

I wonder what the deal is about not clocking the audio converters at
the desired sample rate directly.  Is this another attempt at keeping
folks from working with the 41.8khz CD audio sample rate directly?
