The 'OUCH' message refers to a bit (single dma mode) which is set
because there is no secondary DMA channel defined. There should not be
this error message since you really have single DMA mode. While I fix
things (eg also disable full duplex) the simplest thing you can do is
remove line 

        DDB( if (m & 4) printf("OUCH! reg 9 0x%02x\n", m); );

in ad1848.c


Also for your case I will add the PnP vendor_id to the list of known
ones so you can exploit full PnP features. This will have the side
effect of moving the device from unit 0 to unit 1 which will require
you to change the symlinks /dev/audio, /dev/mixer, /dev/dsp to point
to the new unit.

	Thanks for the report.
