Does anyone know how to get the cs4237b sound card in the Dell Latitude CPi working? I am using openSUSE 10.2.

disable alsa, that worked for me. Remove file sound from /etc/modprobe.d
disable alsa in runlevel editor in yast control center.

After that, it just started playing using OSS. (Maybe you have to run the yast2 sound module before and manually choose the card there. It won't suceed however, so me thinks it is not needed.)

Also, you have to disable some port ranges for pcmcia, else the sound skips:

editthis file: /etc/pcmcia/config.opts

comment (# on beginning of line) or remove lines

include port 0x100-0x3af
include port 0x3ae-0x4ff

(or similar ranges, should yours be different)


Last but not least, to have smooth playback after resume from hibernation, some services have to be restarted:

edit this file: /etc/pm/config

there is this line
SUSPEND_MODULES="button"

just add soundcore there - ie SUSPEND_MODULES="button soundcore"

That was what I've done.


P.S. I installed the OS with boot parameter acpi=off, it might help. (If so, don't forget to remove the parameter after installation, because the system uses installation parameters for regular booting, it seems.)
