After some vain efforts, alsaconf got the snd-cs4232 module loaded for me. I can't play anything though. No sound ever happens. I've read a lot of threads on this matter, but it seams that people were unable to get working sound with this machine for some time now (about 3 years). Personally I got ALSA working with S.u.S.E. 8.0 livecd I borrowed. No success with both 10.2 and 10.1. versions of SUSE.

Some additional information about my system: It is Dell Latitude CPi D300XT - soundcard is Crystal 4237b. specs are at: http://support.dell.com/support/edocs/systems/pmojav/specs.htm [^] I loaded Opensuse 10.3 - kernel 2.6.22.9-0.4. Installation was run with acpi enabled.

I use the cs4232 driver - that was what alsaconf set up. I was only able to get alsaconf detect the chip with acpi off, however after alsaconf configured it, it "works" the same way (which is to say SNAFU) with acpi enabled as well.

The module loads at boot (a click can be heard), and I finaly got alsamixer working (loads and I can adjust controlls), but playback doesn't work.

This is what I get when trying "aplay /opt/kde3/share/sounds/KDE_Startup.wav -t wav -f cd -r 44100":

aplay: pcm_write:1266: write error: Chyba vstupu/výstupu /well, the last part stands for I/O error in czech/

Sometimes aplay terminates and displays this error, the other day it just hangs (ctrl-c needed) and the message appears in dmesg... (I put part of the dmesg below/

Another odd thing: I only have PCM, Line, Mic, Mic boost, Aux, Aux1, Mono, Mono Out, Mono Out, Capture, Mix, Loopback controls in alsamixer - no midi, but more importantly no Master!

I also keep getting a couple of messages about auto calibration time out at boot as well as while resuming from S3 (RAM) and S4 (disk) sleep. See dmesg output bellow.

ALSA sound/core/pcm_lib.c:1717: playback write error (DMA or IRQ trouble?)
