I believe the es1370 has an SB16 compatibility mode (which can be
enabled/disabled?) that listens on SB16 ports, interrupts and DMA
channels and routes the requests back to PCI/es1370 space. I guess if
sb16 loads first, the ports etc are marked in use and the es1370
ignores them. But if es1370 loads first it claims the sb16 io space,
and sb16 chokes.

Speculation, of course...

That card actually seems pretty well identical to the AudioPCI/PCI64
card, except it has another input in the back, presumably so you don't
have to toggle between line-in/rear-out - they are both simultaneously
accessible. Anyway, the es1370 driver works with it... I've been
writing a driver for this card in BeOS based on it being an AudioPCI,
and I confirm that it reacts just like an es1370 with an ak4531
codec. PCI ID is certainly that of the es1370...
