Next thing is that your have a second driver loaded: the snd-cs4236. Do not load this driver. AFAIR, the snd-cs4236 driver should be blacklisted or removed on laptop with the cs4232 chip and PNP BIOS. The cs4236 and cs4232 have the same PNP BIOS id-s. The snd-cs4236 was incorrectly loaded instead of the snd-cs4232 at least on my laptop (old Dell).
Isn't there any way to check this conflict between CS4232 and CS4236? If we can know that the particular card is for snd-cs4232, snd-cs4236 could give a warning and quit...
I have opened my laptop and it has the CS4237B chipset (the one the Dell states for this model). A problem is with ALSA drivers. The snd-cs4232 is the only driver which supports pnpbios. The snd-cs4236 does not so it does not recognize the card.
An ultimate solution would be to merge the snd-cs4236-lib into the wss-lib (as Rene Herman proposed some time ago) then prepare a single driver for all cs423x cards.
