I think Tony's hints indicate all the pitfalls.  The ALSA site has also
quite good documentation, actually:

http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=Cirrus+Logic&card=CS4232&chip=CS4232&module=cs4232

The module options I use (there is a comment somewhere on the above
page, stating "# module options should go here") are the same as Thomas
Hood's (IIRC):

(It has to read snd-cs423_2_, of course...)
