Alsa issue: how to make it work after rebooting

[onemyndseye]

use this command to fix your alsa:

(as root)
dpkg-reconfigure alsa-base



You can add this to the very end of /etc/init.d/knoppix-hd-autoconfigure:

dpkg-reconfigure alsa-base >/dev/null 2>&1




OR:.... Use my script.

reconfigure_alsa.sh

#!/bin/sh
#
# Ripped straight from postinst in the alsa-base package.
#
[ "$UID" != "0" ] && echo "Must be run as root!" && exit 1

echo "Configuring ALSA..."

set -e

MYNAME="$0"

# $* message
warn() { echo "${MYNAME}: Warning: $*" >&2 ; }

# $* message
report_error() { echo "${MYNAME}: Error: $*" >&2 ; }

devfs_is_active()
{
	test -e /dev/.devfsd
}

kernel_is_2_6_or_above()
{
	case "$(uname -r)" in
		1.*|2.[012345]*) return 1 ;;
		*) return 0 ;;

}

(as root)
Copy the above text and paste into a new file named: /etc/init.d/reconfigure_alsa.sh ...

Then issue (as root): ln -s /etc/init.d/reconfigure_alsa.sh /etc/rcS.d/S10reconfigure_alsa


Reboot


Take Care,
