Hmm, do you have udev installed and do you get nodes created to /dev/snd
directory?

So, you were able to hear something? I had some DMA problems with my
OMAP1510 based h6300 and therefore the omap-alsa.c has
#ifdef CONFIG_MACH_OMAP_H6300 in one place. You could try to enable that
also in your board?
For Daniel the AIC23 alsa code however worked with the OSK board without
need for the modifications.
