#  I. Auto-detection of your Aureal Vortex sound card
#
# If for some reason this script fails to guess the type of your
# Aureal card correctly, you can manually override it here.
# Set this to 8810 (Vortex Advantage), 8820 (Vortex 1) or 8830
# (Vortex 2):
#
#CARD=8830
#
# II. VIA Apollo KX133 lock-up issue workaround
#
# If your AMD Athlon system is based on a VIA Apollo KX133 motherboard
# chipset, your system will most certainly lock up shortly after
# you start a playback. To work around this issue please uncomment
# this line:
#
#VIAKX133FIX=yes
