Don't do this.

I have an es1370 (1 card)
# es1370 card
alias sound-slot-0 es1370
alias sound-slot-1 es1370

sound-slot-1 is used by /dev/dsp1 (the card, like yours, has 2 dsps)

What you should do is add sound-slot-2 and 3 in there with the same module

There's none on PCI that you give. The driver looks it up.

Just remember,
/dev/dsp and /dev/dsp1 are the dsps of your first found card,
/dev/dsp2 and /dev/dsp3 are the dsps of your second found card.

If I'm wrong, someone correct me.
