#  simply allows quick switching of pulse-autoconf from either fzf or 
#  from command line switches (e.g. for use with Openbox, etc). Example OpenBox
#  menu at the end of this file.
# 
#  Default presets from pulse-autoconf v 1.5.1 are
#
#   preset="EchoCancellation"
#   preset="EchoCancellationWithSourcesMix"
#   preset="EchoCancellationPlacebo"
#   preset="None"
#
#   No error-checking is done for direct input 
#
