# Gentoo users: add this script to 'boot' run level.
# ==================================================
#
# alsasound This shell script takes care of starting and stopping
# the ALSA sound driver.
#
# This script requires /usr/sbin/alsactl and /usr/bin/aconnect programs
# from the alsa-utils package.

# Rewritten for better support for built-in drivers
#
# 2004.10.29 - Jeremy Huddleston <eradicator@gentoo.org>
# Cleaned up to work better for mixed builtin/module systems
#
# 2004.11.29 - Jeremy Huddleston <eradicator@gentoo.org>
# Added save option thanks to Ben Anderson <roothorick@new.rr.com>
#
# 2005.04.21 - Jeremy Huddleston <eradicator@gentoo.org>
# Added restore option and oss option.
# Cleaned up code to use bash builtins instead of test.
