On my machine:

$ ls /dev | grep dsp
dsp0.0
dsp0.1

i.e no dsp1.0

Could be that the 2 cards are confusing it, as you suggested previously
(they both use the same driver). Can you disable one in the BIOS?

Looks OK.

What does:

$ cat /dev/sndstat

give you?

out which card to use.

I feel pretty sure you'll have better luck disabling one. I have had 2
cards in the same machine before but they used different drivers.
