hi knoppix ppl!
finally i solved my soundcard problem with a real dirrrty hack...

the problem was, that adding alsa=intel8x0 to the boot options didn't help.
furthermore intel8x0m (for the modem) is insmodded before intel8x0 (when calling it with the boot param)...

another problem is that the xsession uses the oss device ("initiating startup sequence") so you can't rmmod the oss i810_audio module during the xsession.

so i put simply the following lines to my "personal settings" knoppix.sh file:

Code:
#!/bin/sh
[ "`id -u`" = "0" ] || { echo "You need root privileges to modify the system!" >&2 ; exit 1; }
[ -d "$1" ] && CONFIGS="$1/configs.tbz"
[ -f "$CONFIGS" ] || CONFIGS="/cdrom/KNOPPIX/configs.tbz"
[ -f "$CONFIGS" ] || CONFIGS="/mnt/floppy/configs.tbz"
if [ -f "$CONFIGS" ]; then
echo "Extracting config archive $CONFIGS..."
tar -jpPtf "$CONFIGS" | while read i; do rm -f "$i"; done
tar -jpPxf "$CONFIGS" ; chown -R knoppix.knoppix /home/knoppix
fi
echo "Starting daemons..."
for i in  cupsys; do [ -x /etc/init.d/$i ] && /etc/init.d/$i start; done
# added by jotzet
rmmod snd_intel8x0m
rmmod i810_audio
modprobe snd_intel8x0
alsa_init
alsa_snddevices
# u could leave the next line out
alsamixer
this is the file which fetches the personal data from a external storage dev.
i couldn't find a solution to set the mixersettings apart from calling alsamixer (alsactl restore isn's supported).

instead of putting the lines to the knoppix.sh file, you could boot with "knoppix26 2" for init 2 and enter the lines manually.

finally i'm able to use skype(out) under knoppix and it works flawlessly.

i know it's a dirty way to do it, but it works for me.
and i hope 4 u 2!
