If your sound card works with alsa
you can add the line
/etc/init.d/alsa-autoconfig
in the boot script /etc/init.d/bootmisc.sh
And alsa ver will be actived at eaxh boot.

Also i suggest to add in the KNOPPIX/usr/local/bin/knx-hdinstall some lines like the folling:

# add alsa activation to bootmisc.sh
# In the boot script /etc/init.d/bootmisc.sh if you add line
# /etc/init.d/alsa-autoconfig
# Alsa server start at boot and it ok for my kde.
# In the KNOPPIX/usr/local/bin/knx-hdinstall of my personalized KNOPPIX I have add some line like:

if checkbootparam alsa >/dev/null 2>&1; then
ALSA_CARD="$(getbootparam 'alsa' 2>/dev/null)"
[ -n "$ALSA_CARD" ] || ALSA_CARD="autodetect"
else
ALSA_CARD="autodetect"
fi

noalsa=""
checkbootparam noalsa && noalsa='#'
checkbootparam noaudio && noalsa='#'
checkbootparam nosound && noalsa='#'
checkbootparam NOALSA && noalsa='#'
checkbootparam NOAUDIO && noalsa='#'
checkbootparam NOSOUND && noalsa='#'

Nice!

[hapbt]

hopefully this appears soon in next knoppix iso update!

Thats a nice idea, but it is the wrong fix.

You just have to run alsa-autoconfig ONCE after an hd-install. (So you could detect it as well and then chroot to it, and do it once.)

Another possibillity is to cp /etc/modutils/1alsa /etc/modutils/alsa-knx-0.9 or similar to /mnt/target/etc/modutils +

cp /etc/modules.conf /mnt/target/etc/

Though you have to add in both choices to bootmisc.sh:

aumix -w 60 -v 60

I have test knx-hdinstall wth the folling uncommented line instead of the line of my late post
on alsa after knx-hdinstall.:

noalsa=""
checkbootparam noalsa && noalsa='# '
checkbootparam noaudio && noalsa='# '
checkbootparam nosound && noalsa='# '

echo "# 2 lignes to start sound server alsa" >>$TR/etc/init.d/bootmisc.sh
echo "# uncomment to start alsa at boot" >>$TR/etc/init.d/bootmisc.sh
echo $noalsa"aumix -w 60 -v 60" >>$TR/etc/init.d/bootmisc.sh

# use Knoppix-generated modutils/1alsa and alsa-0.9-knoppix
cp -af /etc/modutils/1alsa $TR/etc/modutils/1alsa
cp -af /etc/modutils/alsa-0.9-knoppix $TR/etc/modutils/alsa-0.9-knoppix

I was inspired of the folling lignes in knx-hdinstal:

# use Knoppix-generated XF86Config
cp -af /etc/X11/XF86Config $TR/etc/X11/XF86Config
cp -af /etc/X11/XF86Config-4 $TR/etc/X11/XF86Config-4

1alsa and alsa-0.9-knoppix are copied in /etc/modutils/ of the target partition

and "aumix -w 60 -v 60" ais added to bootmis.sh

But sound card not work on reboot on target partition!
So i need more explanation froim fabianx

if checkbootparam alsa
then
echo "# line to unmute the mixer (eso. needed for alsa)" >>$TR/etc/init.d/bootmisc.sh
echo "aumix -w 60 -v 60" >>$TR/etc/init.d/bootmisc.sh
# use Knoppix-generated modutils/1alsa and alsa-0.9-knoppix
cp -af /etc/modutils/1alsa $TR/etc/modutils/1alsa
cp -af /etc/modutils/alsa-0.9-knoppix $TR/etc/modutils/alsa-0.9-knoppix
chroot $TR depmod -a
fi

That should work, or try:

if checkbootparam alsa
then
echo "# line to unmute the mixer (eso. needed for alsa)" >>$TR/etc/init.d/bootmisc.sh
echo "aumix -w 60 -v 60" >>$TR/etc/init.d/bootmisc.sh
chroot $TR /etc/init.d/alsa-autoconfig
fi

Presumably, the purpose of using Knoppix as a Linux hard disk installer is to cut through the installation clutter/delay/problems that so many distros seem to have.

The "correct fix" is to take a snapshot of the Knoppix environment as tweaked by a user after detection of hardware and other boot up issues from the live-on-cd execution and then use those exact settings within a on-the-fly, modified knx-hdinstall script.

You might think it's the "wrong fix", but then again, your frame of reference might be off. After all, a battleship can't intimidate a lighthouse into moving out of its path.
