# script by Ahau <ahau@porteus.org>
# script to change the volume in Porteus-XFCE
# channel is tied to the selected channel in volumeicon, so this requires retrovol (unless you only want to change Master Volume)

#some user editable variables:

#change to 0 if you don't want gtkdialog gui box
show_gui=1

#change icons...

muteicon=/opt/porteus-scripts/extra/icons/audio-volume-muted.svg

# This will search the retrovol configs for the specified volume channel
# this file will not exist unless the user reconfigures retrovol, so it defaults to Master Playback Volume
# if ~/retrovolrc is not found.
