AC' 97 sound card problem...

[Sizu <sizukesa77@tiscali.it>]

Hello, I've installed knoppix 3.3 on my laptop, an Acer TM230 but i can't hear any sound.
Sound card chipset is Intel 802801DB AC'97 and when I type modprobe i810_audio i get this message

modprobe i810_audio
/lib/modules/2.4.22-xfs/kernel/drivers/sound/i810_audio.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.22-xfs/kernel/drivers/sound/i810_audio.o: insmod /lib/modules/2.4.22-xfs/kernel/drivers/sound/i810_audio.o failed

I read in a old post on this list that with alsa soundcard work; I get all necessary file but when I probe module I get the same message

root@whiterabbit:/usr/local/src/alsa-utils-0.9.7# modprobe snd-intel8x0
/lib/modules/2.4.22-xfs/kernel/sound/pci/snd-intel8x0.o: init_module: No such device
