#####
# For use with Intel HDA.
# - Provides full-duplex for the default device via dmix / dsnoop and asym.
# - Forces 44.1kHz sampling rate (instead of 48kHz) for OpenAL compatibility.
#   Note: For this to work "(define sampling-rate 44100)" must be specified in ~/.openalrc also.
#         See http://bugs.gentoo.org/show_bug.cgi?id=193147 for details.
#
# REMEMBER TO STOP ALL APPS USING ALSA AND RUN "/etc/init.d/alsasound restart" AS ROOT!
# Otherwise changes seem not to be picked up correctly sometimes (very confusing ;-)
