# Load the ALSA OSS kernel modules to support OSS applications.
# To use this, set this script as executable (chmod 755 rc.alsa-oss)
# and it will be run from the main rc.alsa script.  Unless you know
# that something requires OSS support, it is better to leave this
# script disabled.  Some applications will try OSS first even though
# they also support ALSA, and will block other applications from
# using audio I/O.
#
# Many programs that use OSS can be run using the aoss wrapper and
# will then use ALSA in a non-blocking way (and will not require
# loading these kernel modules).  Consider trying that before enabling
# these modules.  (See "man aoss")
