Summary:                    Soundchip was not detected
Description: 
I have an HP Omnibook 5700 CTX with some CS423x chip onboard, which is not
detected by alsaconf. I did not find the ids in cs4236.c so I think the
Pnp ID's
must added to this file.

I didn't give you the whole information.

1.

I compiled alsa-driver-1.10.rc3 again -with-debug=full , to see if this
brings more info to the screen.
dmesg tells now after:

ALSA (path to cs423x) cs4236.c:179: CS4232 WSS PnP manual resources are
invalid, using auto config

a new message:

ALSA (path to cs423x) cs4231_lib.c:386: cs4231_mce_down - auto calibration
time out (1)

The noise from the speaker sounds like a farth (I think that hint is very
usefull!!!)

2.

Whne I try to unload the module (modprobe -r snd-cs4232) the kernel says:

Unable to handle kernel NULL pointer dereference at virtual address

Here I'am again!

I'm now using kernel 2.6.16-rc2 and nothing changed, but I found out, that
the oss driver works well, so I try to look what he's doing, look what the
alsa-driver isn't doing and then make the alsa driver doing this.
