# Support for mixer controls in FVWM-Crystal
# Written by: Dominique Michel <dominique_libre@sourceforge.net>
#
# This file contain code for all the mixers.
#
# The original mixers are ALSA mixer (alsamixer, alsamixergui and
# alsamixerguis (a script part of bmpdj)),
# audacious, aumix, cdcd, cmus, mpd, quodlibet and xmms2.
#
# The original controls was written by Maciej Delmanowski <harnir@linux.net.pl>
# at the exception of alsamixer, bindings for multimadia keys
# and dB support by Dominique Michel,
# audacious control by Rafael Antonio Porras Samaniego <spoek@distrobit.net>
# and xmms2 control by Michal Gorny <peres.fvxm@mailnull.com>
#
# Only alsamixer do have direct dB control. This is a must have feature for a professional audio mixer.
# It will be approximated for the other mixers.
# Update: The alsamixer control use now the alsamixer native steps, it was tested
# with card using dB. It should hopefully work for cards without dB support, at the exception of the
# volume tooltip.
#
# Alsamixer support up to eight sound cards. You can choose the one and the volume control in the prefs.
#
# To call the functions, in the menus, it is part of "Popup /Music"
# Button 1: Mouse 4 "Change-Volume-Up"; Mouse 5 "Change-Volume-Down"
# Button 2: Mouse 3 "Menu /Mixer"
# 
# Amixer do have tooltip support now; it show the current volume.
