Info might be easier to find in this forum for the
Alsa Equalizer plugin in Synaptic.
Two files are needed.
For the Alsa-EQ plugin the file reads :
# /etc/asound.conf file for terminal command: $alsamixer -D equal
# Modify the line below if you do not
# want to use sound card 0.
#by default we want to play from more sources at time:
# If you don't want the equalizer to be your
# default soundcard comment the following
# line and uncomment the above line. (You can
# choose it as the output device by addressing
# it with specific apps,eg mpg123 -a equal 06.Back_In_Black.mp3)
Alsa-EQ.desktop file to put in /usr/share/applications reads :
Name=AlsaMixer - EQ
Comment=Advanced Linux Sound Architecture (ALSA) Equalizer
Exec=alsamixer -D equal
The Alsa-EQ.desktop file goes into /usr/share/applications only.
Should appear in the main menu under Sound then. Should fire right
up then after reboot to load the plugin file in /etc/asound.conf
Any question, just post back.
