I assume one dsp is for es1370 and one is for the sb-16

Yes, you can use one sound card or the other. You may hear a difference.

The same as the previous one: write to dsp but never read even the
smallest sample of the sound file possibly by lack of interrupt.

My es1370 is happy with IRQ 9 which is shared with usb-uhci. IRQ 15 is
for ide1 here.
