# By default, drivers for all supported cards will be compiled.
# If you want to only compile for specific card(s), set ALSA_CARDS
# environment to a space-separated list of drivers that you want to build.
# For example:
#
#   env ALSA_CARDS='emu10k1 intel8x0 ens1370' emerge alsa-driver
#
[ x"${ALSA_CARDS}" = x ] && ALSA_CARDS=all
# Need the baselayout 1.7.9 or newer for the init script to work correctly.
