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.

Please help.

Okay,

I found, applied and run it. The chip is detected with alsaconf as a
cs4232 instead cs4236 and changes the modprobe.conf-file.

When I run modprobe snd-cs4232 (slackware 9.0 has no alsa-init-script), I
got a noise from the speakers and the kernel says:

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

The modules are loaded.

Consulting the /proc - files I got:


/proc/ioports

...
0220-022f : CS4232 SB
...
0388-0389 : OPL2/3 (left)
038a-038b : OPL2/3 (right)
...
0534-0537 : CS4231
...


/proc/interrupts

...
5:     0     XT-PIC CS4231
...


/proc/dma

0: CS4231 - 2
1: CS4231 - 1
...


In /proc/asound I have a link CS4236 to card0

/proc/asound/cards
0 [CS4236]: CS4236 - CS4236
            CS4236 at 0x534, irq 5, dma 1&0

/proc/asound/devices
 4: [0- 0]: hardware dependent
16: [0- 0]: digital audio playback
24: [0- 0]: digital audio capture
 0: [0 -0]: ctl
33:       : timer


/proc/asound/card0/id

CS4236


/proc/asound/card0/pcm0c/info

...
id: CS4231
name: CS4236
...


So everything looks fine, but when I start alsamixer I get:

alsamixer: function snd_ctl_open failed for default: No such device


When starting aplay (without options) I get:

ALSA lib confmisc.c:672:(snd_func_card_driver) cannot find caro ´0´
and other "No such device" errors.
